Question

A jogger ran at a rate of 5.4miles per hour , what's the joggers exact rate in feet per minute

Answer 1

The distance ran by the jogger in 1 hour = 5.4 miles
We already know that
1 hour = 60 minutes
1 mile = 5280 foot
So
The distance ran by the jogger in 60 minutes = 5.4 * 5280 foot
                                                                         = 28512 foot
Then
The distance ran by the jogger in 1 minute = (28512/60) foot
                                                                     = 475.20 foot
So the joggers exact rate is 475.20 feet per minute. I hope the procedure is clear enough for you to understand.

Answer 2

   (5.4 mile/hour) x (5,280 feet/mile) x ( 1 hour / 60 minute)

= ( 5.4 x 5,280 / 60)  feet/minute

=        475.2 feet/minute
