Question

Robert climbed 775 steps in 12 1/2 minutes. How many steps did he average per minute?

Answer 1

another way you can think about the equation is by using ratios:

775 x
—— = ——
12.5 1

then cross multiply to make it an algebra equation.

775 * 1 = 12.5x

775/12.5 = x
62 steps = x

Answer 2

775 steps across 12.5 minutes = 775/12.5 = 62 steps per minute
