Question

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

Answer 1

$1hour\ (h)=60\ minutes\ (min)\\\\27\ \dfrac{mi}{h}=27\cdot\dfrac{mi}{60\ min}=\dfrac{27}{60}\ \dfrac{mi}{min}=\dfrac{27:3}{60:3}\ \dfrac{mi}{min}=\huge\boxed{\frac{9}{20}\ mi/min}$
