Question

The fastest a human has ever run is 27 miles per hour. How many miles per minute did the human run?

Answer 1

$27\ \frac{miles}{hour}\\\\ hour=60minutes\\\\ 27*\frac{1miles}{60}=0.45\frac{miles}{minute}\\\\ Human\ run\ 0.45\frac{miles}{minute}.$

Answer 2

$\frac{27mi}{1hr} * \frac{1hr}{60min}= \frac{27mi}{60min}$

27mi/60min=9/20
9mi/20min=xmi/1min
Cross multiply
Divide by 20 on both sides
x=  9/20
