Problem Analysis

We have two cyclists who start simultaneously from two different towns and are moving towards each other. We are given the speed of the first cyclist as 12 km/h and the speed of the second cyclist as 15 km/h. The distance between the towns is 162 km. We need to find out how many hours it takes for the cyclists to meet.

Solution

To find the time it takes for the cyclists to meet, we can use the formula:

Time = Distance / Relative Speed

The relative speed is the sum of the speeds of the two cyclists since they are moving towards each other.

Let's calculate the time it takes for the cyclists to meet.

Calculation

The distance between the towns is 162 km.

The speed of the first cyclist is 12 km/h.

The speed of the second cyclist is 15 km/h.

The relative speed is the sum of their speeds: 12 km/h + 15 km/h = 27 km/h.

Using the formula, we can calculate the time it takes for the cyclists to meet:

Time = Distance / Relative Speed

Time = 162 km / 27 km/h

Time = 6 hours

Answer

The two cyclists will meet after 6 hours.
