Wo trains leave the station at the same time going in opposite directions One of the trains travels at 90 mph and the other is traveling at 120 mph After how many hours will they be 735 miles apart?
Going in opposite directions, they separate at the rate of (90 + 120) = 210 miles per hour.They are 735 miles apart after (735/210) = 3.5 hours.
If two planes leave the same airport at 100 PM how many miles apart will they be at 300 PM if one travels directly north at 150 mph and the other travels directly west at 200 mph?
Plane A travels due north at 150 mph for 2 hours, it will go 300 miles. Plane B travels due west at 200 mph for 2 hours, it will go 400 miles. Draw the two vectors and you will see that they make two sides of a right triangle. The distance between the two planes at the end of two hours is just the hypotenuse of this triangle. You could use the Pythagorean theorem (c^2 = a^2 + b^2) to find the distance...or you could recognise that 300 and 400 are two of a pythagorean triplet (300, 400, 500) and the third number of this triplet is 500. So, the planes will be 500 miles aprt at the end of two hours
Two people running pass each other they continue in opposite directions the first person runs 6 mph the other one is running 10 mph how many minutes will pass before they are 2 miles apart?
7 mins 30 sec. Their combined speeds are 16mph, this is their relative speed to each other. After an hour they will be 16 miles apart. After half an hour 8 miles apart, after 15 minutes 4 miles apart and after 7 mins and 30 seconds they will be 2 miles apart. 7.5 minutes ~ Dawn Ayers
Is 649 miles in 11 hours faster than 442 miles in 8.5 hours?
Yes it is. It is 59 miles per hour, while the other is 52 miles per hour.
Which rate is the greatest 800 miles per 16 hours 1500 miles per 50 hours 600 miles per 15 hours or 900 miles per 20 hours?
Convert them all to the same per x hours and then compare them. You can either convert them all to unit rates (x = 1) or some other rate (eg lcm of 16, 50, 15 and 20). I'll use unit rates: 800 miles per 16 hours = 800 ÷ 16 miles per 16 × 16 hours = 50 mph 1500 miles per 50 hours = 1500 ÷ 50 miles per 50 ÷ 50 hours = 30 mph 600 miles per 15 hours = 600 ÷ 15 miles per 15 ÷ 15 hours = 40 mph 900 miles per 20 hours = 900 ÷ 20 miles per 20 ÷ 20 hours = 45 mph 50 mph is the greatest unit rate → 800 miles per 16 hours is the greatest rate. --------------- The rates can be ordered: 50 > 45 > 40 > 30 → 800 miles per 16 hours > 900 miles per 20 hours > 600 miles per 15 hours > 1500 miles per 50 hours.

Two cars leave town at the same time traveling in opposite directions One car travels at a rate of 60 miles per hour The other car travels at a rate of 70 miles per hour How far apart will the two?

Two cars leave town at the same time going in the same direction One travels 55 mph and the other travels 48 mph In how many hours will they be 49 miles apart?
x will be the time in hours, so your equation is 55x+48x=49You can add the like terms together to get 103x=49You can divide by 103 to get x=49/103, or about 0.4757281 hours, or 28 minutes and 32.62116 seconds.

How long will it take them to be 650 miles apart... someone plz answer now
If two trains are 2000 miles apart on the some track one travels east at a velocity of 150 mph the other travels west at a velocity of 100 mph how long will it take for them to meet?
The closing velocity is speed1 plus speed2, so the trains are moving toward each other at 250 mph. 2000/250 = 8. The trains will meet in 8 hours.
When two cyclists begin traveling in the same direction on the same bike path One travels at 15 miles per hour and the other travels at 12 miles per hour when will the cyclists be 10 miles apart?
To find when the cyclists will be 10 miles apart, you can set up a distance equation. Since they are traveling in the same direction, the relative speed at which they are moving apart is 15 - 12 = 3 mph. So, the time it will take for them to be 10 miles apart is 10 miles / 3 mph = 3.33 hours.
If two planes leave the same airport at 1 o'clock PM how many miles apart will they be at 3 o'clock PM if one travels directly north at 150 mph and the other travels directly west at 200 mph?
One plane will be 300 miles (150 mph * 2hours ) north. The other plane will be 400 miles (200 mph * 2hours ) west. This makes a right triangle with sides of 300 and 400. If you know your right triangles, you will know that the hypotenuse will be 500 miles. (3-4-5 triangle) If not hypotenuse = √(3002+4002) = 500 miles They will be 500 miles apart.

Two cyclists begin traveling in the same direction on the same bike path one travels at 15 miles per hour and the other travels at 12 miles per hour when will the cyclists be 10 miles apart?
Answer:3 1/3 hours or 3 hours and 20 minutesSolution:distance = velocity x timethe distance travelled by the first cyclist = 15 x timethe distance travelled by the second cyclist = 12 x timethe difference distance = 15 x time - 12 x timethis difference will be 10 miles when15 x time - 12 x time = 103 x time = 10time = 10/3 = 3 1/3 hours= 3 hours and 20 minutes.
