Question

If a vehicle is going 72 mph, how many feet does the vehicle travel in one second assuming the driver's reaction time is one second?

a) 52.8 feet
b) 105.6 feet
c) 120 feet
d) 158.4 feet

Answer 1

To determine the distance a vehicle travels in one second, convert the speed from mph to fps by multiplying by 5280/3600. For a vehicle traveling at 72 mph, the distance traveled in one second is 105.6 feet.

Step-by-step explanation:

To determine the distance a vehicle travels in one second, we need to convert the speed from miles per hour (mph) to feet per second (fps). Since 1 mile is equal to 5280 feet and 1 hour is equal to 3600 seconds, we can calculate as follows:

Speed in fps = (Speed in mph)*(5280/3600)

So, for a vehicle traveling at 72 mph:

Speed in fps = (72)*(5280/3600) = 105.6 fps

Therefore, the vehicle travels 105.6 feet in one second assuming the driver's reaction time is one second. The correct answer is b) 105.6 feet.
