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:

The length on the ground will be ...

(24·10^-2 m)·(1.5·10^6) = 36·10^4 m = 360·10^3 m = 360 km

The length of river is 360km

Explanation:

Length on the map of Severn river = 24cm

Scale on the map = x:y axis

                               =1:1500000

Where y is the length  

Hence 1 cm= 15 km

Therefore

Length of the river

=2415

=360 km

Hence the length of river is 360 km
