You drive a car 2 hours at 40 miles per hour 2 hours at 60 miles per hour how many miles will you travel?
If you drive a car at 40 miles per hour for two hours,then the distance covered will be 80 miles.If you drive the car for another 2 hours at 60 miles per hour ,then you will cover another 120 miles.The total distance you will cover is thus 80 miles + 120 miles = 200 miles.
A car traveling 30 miles per hour and another car traveling 41 miles per hour how long before the car rear ends the other car?
Are they travelling on the same road? In the same direction? Which car is in front? How far apart were they to start with? Is the driver in the faster car blind?
If a motorcycle traveling at seventy mile per hour overtakes a car traveling at forty miles per hour that had a three hour head start how far from starting point are the two vehicles?
There are several ways of answering this question:In all cases, the car, with a three hour head start is 3*40 = 120 miles in front.Method I:The motorcycle is travelling at a relative speed of 70-40 = 30 mph. At this speed it has to make up the distance of 120 miles. This will take 120/30 = 4 hours.At a speed of 70 mph, the motorcycle will have travelled 4*70 = 280 miles.Method II:At time t hours from when the motorcycle starts, the car is at 120 + 40*t miles.At that time the motorcycle is at 70*t miles.These two must be equal so 120 + 40*t = 70*tso 120 = 30*t so that t = 4.Then, as before, the motorcycle is 4*70 = 280 miles from its start.Method III: ;DInvoke Zeno's paradox.When the motorcycle starts, the car is at a point 120 miles ahead. It takes the motorcycle some time to get to that point. During that time the car has moved on a further distance. It then takes the motorcycle some more time to get to that point. But by then the car has moved on by yet another small distance. And so on. How can the motorcycle hope to catch up if, by the time it gets to where the car WAS, the car has moved forward some more?
If a car travels 16 miles in 30 minutes how fast is the car traveling?
32 miles per hour. The speed at which the car is travelling is the distance in miles that the car travels per hour. If the car travels 16 miles in 30 minutes it should then travel twice as far in one hour, since one hour is twice as long as 30 minutes (half an hour). So, the car travels 2 * 16 miles per hour, which equals 32 miles per hour.
Help ruth's car traveled 120 miles during the first race during the second race it traveled 124 miles if the car averaged 123 miles over the first three races how far did it travel during the thi?
(120+124+#MILESFROM3RDRACE#)/3 = 123so120+124+#MILESFROM3RDRACE# = 123 * 3it follows that#MILESFROM3RDRACE# = (123 * 3) - 120 -124You can do the math since the equation is worked out.
