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

Answer:

$96.8\frac{feet}{second}$

Step-by-step 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

$66\frac{miles}{hour}$

convert to feet per second

$66\frac{miles}{hour}=66(\frac{5,280}{3,600})=96.8\frac{feet}{second}$
