Mike is riding his bike at 15 miles perhour. What is his speed in feet per second? (Use 5280 feet in each mile)

15 times 5280 = 792000

Now divide that by 3600 to get feet per second!

15 miles = 15 miles x ( 5280 feet / mile = 79 200 feet

1 hour = 1 hour x ( 60 minutes / hour ) x ( 60 seconds / minute ) = 3600 seconds

15 miles per hour = 79 200 feet per 3600 seconds = 22 feet per second

"per" means "divided by"

*Mike is riding his bike at 15 miles perhour. What is his speed in feet per second? (Use 5280 feet in each mile)*

You already have your mathematically computed answer; I'm just going to tell you a way to get an __estimate__.

When you have miles per hour, multiply it by 1.5 to get feet per second. In this problem the estimate is **15 x 1.5 = 22.5**.

The accurate answer geno gave you was 22 , this estimate method gives you 22.5. Close enough for government work.
