Calculation of Travel Time

To calculate the time it takes for tourists to travel from point A to point B, we need to consider the scale of the map and the speed at which they are moving.

Given: - Speed of tourists: 5 km/h - Distance on the map from A to B: 4 cm - Map scale: 1:100000

To find the actual distance between A and B, we need to convert the distance on the map to real-world units. We can do this by multiplying the map distance by the scale factor.

The scale factor is the ratio of the real-world distance to the distance on the map. In this case, the scale factor is 1:100000, which means that 1 cm on the map represents 100000 cm (or 1 km) in the real world.

To find the real-world distance between A and B, we can use the following formula:

Real-world distance = Map distance * Scale factor

Substituting the given values:

Real-world distance = 4 cm * 100000 = 400000 cm = 4000 m = 4 km

Now that we have the real-world distance, we can calculate the travel time using the formula:

Travel time = Distance / Speed

Substituting the values:

Travel time = 4 km / 5 km/h = 0.8 hours

Therefore, it will take the tourists approximately 0.8 hours to travel from point A to point B.

Please note that the above calculations are based on the given information and assumptions.
