Answer 2

Problem Analysis

Two tourists are walking in opposite directions at speeds of 4 km/h and 5 km/h. We need to find out how many hours it will take for the distance between them to be 36 km.

Solution

Let's denote the time it takes for the tourists to meet as t hours. The total distance covered by both tourists will be equal to the distance between them when they meet.

The distance covered by the first tourist is given by the formula: distance = speed * time. Similarly, the distance covered by the second tourist is also given by the same formula.

We can set up the following equation to solve for t: 4t + 5t = 36

Calculation

Solving the equation: 4t + 5t = 36 9t = 36 t = 36 / 9 t = 4

Answer

The distance between the two tourists will be 36 km after 4 hours.
