Calculation of the Scale of the Map

To find the scale of the map, we need to determine the actual distance between the two populated areas and the corresponding distance on the map.

Given: - The motorcyclist traveled the distance between the two populated areas in 1 hour and 24 minutes, at a speed of 40 km/h. - The length of the line representing the distance between the two populated areas on the map is 1) 7 cm and 2) 4 cm.

To calculate the scale of the map, we can use the formula:

Scale = Actual Distance / Map Distance

Let's calculate the scale for both cases:

1) For the map distance of 7 cm: - The actual distance traveled by the motorcyclist is 40 km/h * (1 hour + 24 minutes) = 40 km/h * (1.4 hours) = 56 km. - Scale = 56 km / 7 cm = 8 km/cm.

2) For the map distance of 4 cm: - The actual distance traveled by the motorcyclist is still 56 km. - Scale = 56 km / 4 cm = 14 km/cm.

Therefore, the scale of the map is either 8 km/cm or 14 km/cm, depending on the length of the line representing the distance between the two populated areas on the map.
