Problem Analysis

We are given that a cyclist is traveling at a speed of 15 kilometers per hour, and after 3 hours, a motorcyclist starts chasing the cyclist with a speed that is 4 times greater than the cyclist's speed. We need to determine how long it will take for the motorcyclist to catch up to the cyclist.

Solution
