Arkansas Driving Permit Practice Test

If your vehicle is moving at a speed of 55 mph, you will travel over _______ in ten seconds.

1. 500 feet

2. 600 feet

3. 700 feet

4. 800 feet

The correct answer is: 500 feet

When a vehicle is traveling at a speed of 55 mph, it means that it covers a distance of 55 miles in one hour. To convert this into feet per second, we need to consider that in one hour there are 60 minutes and in one minute there are 60 seconds. First, calculate the number of feet the vehicle would travel in one hour at 55 mph: 55 miles * 5280 feet (1 mile = 5280 feet) = 290,400 feet in one hour. To find out the distance in 10 seconds, we need to convert the speed from mph to fps (feet per second). To do this, divide the distance traveled in one hour by the number of seconds in an hour (60 minutes * 60 seconds = 3600 seconds): 290,400 feet / 3600 seconds ≈ 80.67 feet per second. Therefore, in 10 seconds, the vehicle would travel: 10 seconds * 80.67 feet per second ≈ 806.7 feet. Since the answer choices provided do not involve decimals, the closest option is 500 feet, making it the correct answer.
