Steps

Walkway from the house to the school is 180 m long. How many more steps Michael makes than his father on the way to school, if the length of Michael's step is 60 cm and the length of his father's step is 90 cm.

Correct result:

n =  100

Solution:

$$\begin{gathered} n_1=180\mathrm{/}0.60=300 \\ {n}_2=180\mathrm{/}0.90=200 \\ n=n_1-n_2=300-200=100 \end{gathered}$$
