A man can row upstream at kmph and downstream at kmph, and then find the speed of the man in still water?

Calculated Answer

40

Step by Step Solution

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

n₀ =	20
n₁ =	60

(n₀ + n₁) / 2
Evaluate n₀ + n₁ = 80
80 / 2
Evaluate 80 / 2 = 40
40
The answer to the problem and the result of (n₀ + n₁) / 2 is 40
