1 mile = 5280 ft...so 72 miles = (72 * 5280) = 380160 ft
60 seconds in a minute....60 minutes in an hr...(60 *60) = 3600 seconds in an hr.

380160 / 3600 = 105.6 ft per second <==

The speed of the truck in feet per second will be 105.6 ft per second.

What is unit conversion?

To convert any unit into another is called a unit conversion.

In order to convert units, we need to care about their dimensions their dimension should not be changed.

For example conversion of a kilometer to a meter is to multiply by 1000 but meter and kilometer both unit is for distance only.

Another example could be kilo gram to gram.

1 mile = 5280 feet

And

1 hour = 60 minutes

1 hour = 60 × 60 seconds = 3600 seconds

Now

Given the speed of the truck is

⇒ 72 miles/hour

⇒ 72 × 1 mile/1 hour

⇒ 72 ×  5280 feet/3600 seconds

⇒  105.6 feets/second

Hence "The speed of the truck in feet per second will be 105.6 ft per second".
