Question

A boat travels 60 kilometers upstream in 3 hours and covers the same distance of 60 kilometers downstream in 2 hours. What is the speed of the boat in still water?

This question was previously asked in
SSC CGL 2025 Tier 2 Paper 1 Question Paper (19-Jan-2026)
The correct answer is

25 km/h

Step 1 – Find upstream and downstream speeds:

Upstream speed \(= \dfrac{60}{3} = 20\) km/h
Downstream speed \(= \dfrac{60}{2} = 30\) km/h

Step 2 – Speed in still water:

\(= \dfrac{\text{Upstream} + \text{Downstream}}{2} = \dfrac{20 + 30}{2} = 25\) km/h

Hence, the speed of the boat in still water is 25 km/h.
