Q. 107

# <span lang="EN-GB

Answer :

Let the steamer speed will be x

Downstream speed = (x + 1)

Distance between the points = 5(x-1)(i)

Upstream speed = (x-1)

Distance between the points = 6(x-1)(ii)

on solving (i) and (ii)

5(x + 1) = 6(x-1)

5x + 5 = 6x-6

5x-6x = -6-5

-x = -11

x = 1

The steamer speed will be 11km/hr
