Question

two friends race. The first friend gets a head start and runs at a steady rate of 0.20 miles per minute. The second friend waits 1 minute and then runs at a steady rate of 0.25 mi per minute. how long will it take for the second friend to catch up with the first one

Answer 1

Here, we want to calculate the time in minutes it will take for the second friend to catch up with the first.

What this mean is that how long in minutes will it take for them to have traveled the same distance.

Let the number of minutes be x

Mathematically;

distance = speed * time

So in x minutes, the distance the first friend will have traveled will be;

distance = 0.20 miles per minutes * x minutes = o.
