Given that the scale for the map is

1: 50000

means that 1 centimter on the map represents 50000 units on the ground

the units may be kilometers

then what you do is to multiply the distance from A to B by 50000

ie 49 * 50000 = 2450000unit on the

but remember to confirm the units used

if kilometers or miles.
