Question

The average speed of a car on a stretch of interstate is 70 miles per hour. Convert this rate to feet per second.

Answer 1

Answer:

102. 66 feet / Second

Step-by-step explanation:

To do conversion change miles into feet and hour into second.

One foot is 5280 feet

And an hour is 3600sec

70 miles / Hour

70 * 5280feet / 3600 second

369600 feet / 3600seconds

Then simplify

102. 66 feet / Second

Answer 2

Speed given

• 70mph

1 mi=5280ft

1h=3600s

So convert

• 70×5280ft/3600s
• 7×528ft/36s
• 102.67ft/s
