If 2 identical cars crash and each is traveling at 50 mph is the impact speed 50 mph or 100 mph and why?
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.
How long would it take a car traveling 50 mph to go 2600 miles?
52 hours.
A pickup can travel 300 miles in the same time that a car going 10 mph faster can travel 350 miles How fast is the car traveling?
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.
How much time will you save by traveling 4.5 miles at 50 mph instead of 40 mph?
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
What total distance will be covered by traveling at 50 mph for 75 minutes?
Mandy is driving north of 50km/he. If his sister is driving another car at a velocity of -25km/hr, in what direction is she driving?
