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.
the trains speed is 85 miles an hour the answer is very simply the only thing that you need to do is divide 1020 by 12 and you get 85
Then the speed of the slower train in miles per hour is eight more than 380 divided by the number of hours the trains have been traveling. If you want a more precise answer, you need to supply more data.
24 miles apart
average velocity = miles/hours = (100 + 30)/(2 + 1) = 130/3 ≈ 43.33 miles/hour
Acceleration = Change in Velocity / Change in Time a = (Final Velocity - Initial Velocity) / (Final Time - Initial Time) = (55-0)/(5-0) = 55/5 a = 11 m/s^2
3.5 hours [A+]
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.
170 miles per hour
260 miles an hour
They are moving apart at 70 miles per hour - 30 plus 40. Therefore, in 3 hours they will be 210 miles apart.
The velocity of the car is 32 mph
The International Space Station travels at orbital velocity which is 5 miles per second, or approximately 17,500 miles per hour.
The velocity is 83 miles per hour in some, unspecified, direction. Remember, velocity is a vector, so the direction needs to be specified.
660/9 miles per hour = 73.33... mph
the trains speed is 85 miles an hour the answer is very simply the only thing that you need to do is divide 1020 by 12 and you get 85
Then the speed of the slower train in miles per hour is eight more than 380 divided by the number of hours the trains have been traveling. If you want a more precise answer, you need to supply more data.
If a car travels between two towns that are 80 miles apart in 2 hours, they travel at a rate of 40 miles per hour.
