Question

On a map 0.8 cm represents 8 km. How much distance will be represented by 4 cm?

Answer 1

1cm=10km
therefore,4 cm=10×4=40 km

Answer 2

8km = 8,00,000 cm

if scale of 0.8cm = 8,00,000 cm

=) 1cm scale = 8,00,000/0.8 = 10,00,000

hence 4cm scale on map has a real distance of 4*10^6 cm or 40km.
