Respuesta :
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 <==
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".
