Question

A car is driving at a speed of 40 mi/h. What is the speed of the car in feet per minute?

Answer 1

The answer is 3520 per minute.. because there is 5280 feet in a mile, then you x that by 40 since there's 40 miles. Then you divide by 60 cause there's 60 minutes in an hour.

Answer 2

we know that

`1\ mile=5,280\ feet\\ 1\ hour=60\ min`

we have

`40(miles)/(hour)`

Step
`1`

Convert
`(miles)/(hour)` to
`(feet)/(hour)`

`40(miles)/(hour)=40*5,280=211,200(feet)/(hour)`

Step
`2`

Convert
`(feet)/(hour)` to
`(feet)/(min)`

`211,200(feet)/(hour)=211,200/60=3,520(feet)/(min)`

therefore

the answer is

`3,520(feet)/(min)`
