The scale of a map is 1:20, 000. A tunnel measures 0.48 cm on the map. Calculate the actual length in metres of the tunnel.

Answers

1: 20 000 means 1 cm on the

map represents 20 000 cm on the

ground

if 1 cm = 20 000 cm
o.48 cm = x

x = 0.48 x 20 000

0.48 x 20 000

x = $\frac{0.48 \times 20 000}{100}$ = 96

the actual length of the tunnel

= 96 metres
