Question

The longest river in the UK is the river Severn which has a length of 24 cm on a map. If the map is drawn at a scale of 1:1,500,000, then how many kilometers is the river actually?

Answer 1

360 km

Explanation:

we know that

The scale of the map is

1:1,500,000

That means

1 cm on a map ------> represent 1.500.000 cm in the actual

or

1 cm on a map ------> represent 15,000 m in the actual

or

1 cm on a map ------> represent 15 km in the actual

therefore

In this problem

24 cm on a map-------> represent 24*15=360 km actually
