Problem Analysis

We have two marathon runners who start at the same time and walk in opposite directions. One runner walks at a speed of 12 km/h, while the other walks at a speed of 10 km/h. We need to determine how many hours it will take for the distance between them to be 44 km.

Solution

To find the time it takes for the distance between the two runners to be 44 km, we can use the formula:

Time = Distance / Relative Speed

The relative speed is the sum of the speeds of the two runners, as they are moving in opposite directions.

Let's calculate the time it takes:

Relative Speed = 12 km/h + 10 km/h = 22 km/h

Time = 44 km / 22 km/h = 2 hours

Therefore, it will take 2 hours for the distance between the two runners to be 44 km.

Answer

It will take 2 hours for the distance between the two marathon runners to be 44 km.
