A swimmer can swim in still water at 4 km/h.

A swimmer can swim in still water at 4 km/h. If the speed of the water current is 2 km/h, how many hours will the swimmer take to swim against the current for 3 km?

Answer/Solution

1.5

Steps/Work

The swimmer can swim against the current at a speed of 4-2 = 2 km/h.
The time it will take is 3/2 = 1.5 hours.
The answer is A.

A swimmer can swim in still water at km / h. If the speed of the water current is km / h, how many hours will the swimmer take to swim against the current for km?

Calculated Answer

1.5

Step by Step Solution

In order to solve problem, you must evaluate n₂ / (n₀ - n₁).

n₀ =	4
n₁ =	2
n₂ =	3

n₂ / (n₀ - n₁)
Evaluate n₀ - n₁ = 2
n₂ / 2
Evaluate n₂ / 2 = 1.5
1.5
The answer to the problem and the result of n₂ / (n₀ - n₁) is 1.5
