In a race, a frog tried to catch up with a rabbit which started 162m ahead of the frog. For every 3.8m jump that the frog made, the rabbit made a 0.8m jump at the same time. How many jumps would the frog have to make in order to catch up with the rabbit? I understand the way of solving this question would be,
To find the difference, after that, to find the amount of steps:
$162 ÷ 3 = 54 steps$
But I do not know how to explain my workings. My question is that how should I explain my workings to my younger brother so that he understands?
