How many feet per second does a vehicle travel for every mile per hour?

To determine how many feet per second a vehicle travels for every mile per hour, you can use the conversion factors between miles, feet, and hours.

1 mile is equal to 5,280 feet, and 1 hour is equal to 3,600 seconds. Therefore, when you convert miles per hour to feet per second, the calculation is as follows:

First, you start with the distance:

• 1 mile = 5,280 feet.

Then you convert the time:

• 1 hour = 3,600 seconds.

To find the number of feet per second for each mile per hour, you can set up the equation:

Feet per second = (Feet in a mile) / (Seconds in an hour)

Plugging in the values gives:

Feet per second = 5,280 feet / 3,600 seconds = 1.47 feet per second.

This calculation correctly shows that when a vehicle is traveling at a speed of one mile per hour, it covers approximately 1.47 feet each second, making this the correct answer. Understanding this conversion is crucial for law enforcement officers as they frequently need to interpret speed in various contexts.
