RRB Group D Mock Test - 14 - Question 5

A motor boat whose speed is 15 km/hr in still water goes 30 km downstream and comes back in 4 hrs and and 30 minutes. Determine the speed of the stream.

Detailed Solution for RRB Group D Mock Test - 14 - Question 5

Let x km/hr be the speed of water
The speed of motor boat in still water is 15 km/hr, therefore, its speed downstream is (15 + x) km/hr and the speed upstream is (15 - x) km/hr
Time taken for given 30 km downstream = 30/(15 + x)    hours
Time taken for going 30 km upstream = 30/(15 - x) hours
Since the total time is given to be 4 hours 30 minutes
∴ 30/(15 + x)  + 30/(15 - x)  = 9/2 hours (given)

or 1800 = 9(225 - x2)
or 200 - 225 + x2 = 0
or x2 = 25
⇒ x = 5, - 5
∴ x = 5 [as x cannot be negative so x = -5 is rejected]
Hence the speed of water = 5 km/hr
