Question

What is 3 miles per minute expressed in feet per minute? Recall that 1 mile is 5,280 feet.

Answer 1

So you say 1 mile = 5280 feet, therefore, there would be 15, 840ft/min.

Answer 2

Two ways to solve:

1)

Data:
3 miles/minutes → 950400 feet/hour
1 mile → 5280 feet

Therefore:
$\frac{950400}{5280} = 180\:miles/hour$

180 miles/hour → 15,839.....≈ 15,840 feet per minute


2) Converting Directly:

3 miles/minutes → 15,840 feet per minute
