Question

9:39 PM A truck travels on a highway at a speed of 66 miles per hour. What is the speed of the truck in feet per second? Round your answer to the nearest tenths place (second decimal place).

Answer 1

`96.8(feet)/(second)`

Explanation:

Remember that

`1\ mile =5,280\ feet`

To convert miles to feet multiply by 5,280

`1\ hour =3,600\ sec`

To convert hours to seconds multiply by 3,600

we have

`66(miles)/(hour)`

convert to feet per second

`66(miles)/(hour)=66((5,280)/(3,600))=96.8(feet)/(second)`
