Answer 1

Problem Analysis

We are given that a motorist and a rider set off from a village in opposite directions at the same time. We need to determine the distance between them after 2 hours, given that the motorist's speed is 75 km/h and the rider's speed is 5 times less.

Solution

To solve this problem, we can use the formula: distance = speed * time.

Let's calculate the distance traveled by the motorist and the rider separately.

The motorist's speed is given as 75 km/h. So, in 2 hours, the motorist will travel a distance of 75 km/h * 2 h = 150 km.

The rider's speed is 5 times less than the motorist's speed. Therefore, the rider's speed is 75 km/h / 5 = 15 km/h. In 2 hours, the rider will travel a distance of 15 km/h * 2 h = 30 km.

Since the motorist and the rider are traveling in opposite directions, the distance between them after 2 hours will be the sum of the distances traveled by each of them. Therefore, the total distance between them will be 150 km + 30 km = 180 km.

So, after 2 hours, the motorist and the rider will be 180 km apart from each other.

Answer

The motorist and the rider will be 180 km apart from each other after 2 hours.
