Problem Analysis

We are given that a pedestrian and a cyclist start simultaneously from two different points, and we need to find the distance the cyclist will travel before meeting the pedestrian. The distance between the two points is 24 km, and the pedestrian's speed is 4 km/h, while the cyclist's speed is 12 km/h.

Solution

To find the distance the cyclist will travel before meeting the pedestrian, we need to determine the time it takes for them to meet. We can use the formula:

Time = Distance / Speed

Let's calculate the time it takes for the pedestrian and the cyclist to meet.

The time it takes for the pedestrian to meet the cyclist is given by:

Time = Distance / Speed = 24 km / 4 km/h = 6 hours Now, we can calculate the distance the cyclist will travel in 6 hours:

Distance = Speed * Time = 12 km/h * 6 hours = 72 km

Therefore, the cyclist will travel 72 km before meeting the pedestrian.

Answer

The cyclist will travel a distance of 72 km before meeting the pedestrian.
