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?

360 km

Step-by-step 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

your answer would be 10x - 1
