Problem Analysis

We have two cyclists traveling towards each other from two different towns. The speed of one cyclist is 14 km/h, and the speed of the other cyclist is 10 km/h. We need to find the distance between the towns and how much closer they will be to each other after 1 hour and after 30 minutes.

Solution

To find the distance between the towns, we can use the formula: distance = speed * time.

Let's calculate the distance between the towns first.

The first cyclist's speed is 14 km/h, and the second cyclist's speed is 10 km/h. Since they are traveling towards each other, their speeds should be added together.

The total speed of the two cyclists is 14 km/h + 10 km/h = 24 km/h.

To find the distance, we need to multiply the total speed by the time they have been traveling, which is 3 hours.

The distance between the towns is 24 km/h * 3 hours = 72 km.

Now let's calculate how much closer they will be to each other after 1 hour and after 30 minutes.

After 1 hour, the first cyclist will have traveled 14 km/h * 1 hour = 14 km, and the second cyclist will have traveled 10 km/h * 1 hour = 10 km.

The total distance covered by both cyclists after 1 hour is 14 km + 10 km = 24 km.

Therefore, after 1 hour, they will be 72 km - 24 km = 48 km closer to each other.

After 30 minutes, the first cyclist will have traveled 14 km/h * 0.5 hour = 7 km, and the second cyclist will have traveled 10 km/h * 0.5 hour = 5 km.

The total distance covered by both cyclists after 30 minutes is 7 km + 5 km = 12 km.

Therefore, after 30 minutes, they will be 72 km - 12 km = 60 km closer to each other.

Answer

The distance between the towns is 72 km. After 1 hour, the cyclists will be 48 km closer to each other, and after 30 minutes, they will be 60 km closer to each other.
