depends on how much time
If one hour has passed then 50 miles
can be found by the formula of rate x time = distance
The impact speed for each car is 50 mph. During the crash, both cars are accelerated from a speed of 50 mph to zero, hence the impact speed is 50 mph. The relative speed between each car, however, is 100 mph.
To determine how long it will take the car to overtake the truck, first calculate the relative speed between them. The car is traveling 70 mph and the truck is at 50 mph, so the car is gaining on the truck at a rate of 70 - 50 = 20 mph. Since the car is 20 miles behind the truck, it will take 20 miles ÷ 20 mph = 1 hour for the car to overtake the truck.
We know that the time traveled is 5 hours, since a car going 10 mph faster travels an extra 50 miles over the same amount of time.Dividing 300 miles by 5 hours, we get 60 mph. Since the car is traveling 10 mph, the car is traveling 70 mph.
52 hours.
Distance = Rate * Time or, for our purpose Time = Distance/Rate at 50 mph Time = 4.5 miles/50 mph = 0.09 hours = 5.4 minutes ----------------------------- at 40 mph Time = 4.5 miles/40 mph = 0.1125 hours = 6.75 minutes ---------------------------------------------------- 6.75 - 5.4 = 1.35 minutes saved
120 minutes = 2 hours2 hours x 50 mph = 100 miles.

A car traveling at 50 mph covers 73.3 feet per second.

50 mph = 50 miles per 60 minutes = 50*105/60 miles in 105 minutes = 87.5 miles.
If a car is traveling at 5 miles per hour then it will travel 5 miles in one hour. At 50 mph it will take 6 minutes.
