Calculate the speed of a boat in still water (in km/hr) if in one hour, the boat goes 10 km/hr downstream and 4 km/hr upstream.

Answer/Solution

7 kmph

Steps/Work

Speed in still water = (10 + 4)1/2 kmph = 7 kmph.

Calculate the speed of a boat in still water ( in km / hr ) if in one hour, the boat goes km / hr downstream and km / hr upstream.

Calculated Answer

7

Step by Step Solution

In order to solve problem, you must evaluate (n₀ + n₁) / 2.

n₀ =	10
n₁ =	4

(n₀ + n₁) / 2
Evaluate n₀ + n₁ = 14
14 / 2
Evaluate 14 / 2 = 7
7
The answer to the problem and the result of (n₀ + n₁) / 2 is 7
