What are Boat and Stream Questions?

Boat and Stream questions are based on the concept of relative speed. These questions involve a boat moving in water where the water current (stream) also has its own speed.

In such questions, the speed of the boat changes depending on the direction of the current.

• Downstream: When the boat moves in the same direction as the stream.
• Upstream: When the boat moves against the direction of the stream.

Since the stream assists the boat while moving downstream and resists it while moving upstream, the speed changes accordingly.

Important Boat and Stream Formulas

Understanding the formulas is the key to solving these questions quickly.

Downstream Speed

Downstream Speed = Speed of Boat in Still Water + Speed of Stream

Upstream Speed

Upstream Speed = Speed of Boat in Still Water – Speed of Stream

Boat Speed in Still Water

Speed of Boat in Still Water = Downstream Speed + Upstream Speed

Stream Speed

Speed of Stream = Downstream Speed – Upstream Speed

These formulas are frequently used in competitive exams, so candidates should memorize them for quick calculations.

Example Boat and Stream Question

Question:
A boat takes 3 hours to travel 24 km downstream and 4 hours to travel the same distance upstream. Find the speed of the boat in still water.

Solution:

Downstream Speed = 24 ÷ 3 = 8 km/hr
Upstream Speed = 24 ÷ 4 = 6 km/hr

Boat Speed in Still Water
= (8 + 6) / 2
= 7 km/hr
