Question
The time required by a boat to travel (x – 40) km against
the stream is equal to the time it takes to go (2x – 80) km with the stream. If the speed of the boat is 14 km/h and the stream flows at 2 km/h, find the value of ‘x’.Solution
ATQ,
(x – 40)/(14 – 2) = (2x – 80)/(14 + 2)
(x – 40)/12 = (2x – 80)/16
16x – 640 = 24x – 960
8x = 320
x = 40
So, the value of ‘x’ is 40 km.
