Answer 2

Problem Analysis

We are given the following information: - Maxim and Sasha left school with a speed of 50 m/minute. - Roma left after them, 6 minutes later, with a speed of 80 m/minute.

We need to determine how many minutes it will take for Roma to catch up with Maxim and Sasha.

Solution

To solve this problem, we can set up an equation based on the relative speeds of Roma and Maxim/Sasha.

Let's assume that it takes t minutes for Roma to catch up with Maxim and Sasha. During this time, Maxim and Sasha would have covered a distance of 50t meters. Roma, on the other hand, would have covered a distance of 80(t - 6) meters, as he started 6 minutes later.
