Question

A steamer goes
downstream and covers the
distance in 4 hours. While it
covers the same distance
upstream in 5 hours. If the
speed of stream is 2 km/hr.
Find the speed of steamer​

Answer 1

Answer:

ANSWER

Let the speed of the steamer in still water be x km/h.

Then, the speed downstream =(x+2) km/h

and the speed upstream =(x−2) km/h

Given, distance covered in 4 hours downstream = distance covered in 5 hours upstream

∴4(x+2)=5(x−2)

⇒4x+8=5x−10

⟹4x−5x=−10−8

[Transposing 5x to LHS and 8 to RHS]

⟹−x=−18 or x=18km/h
