Answer 1

Answer:

A swimming pool is 50 meters long. How many times will a swimmer traverse the entire length of the pool if he needs to cover 200 meters

Answer 2

The swimmer need to swim 4 times along pool to cover 200 meters.

Given:

Length of the swimming pool = 50 meter

To find:  

Number of times turns to cover 200 meters

Solution:

Given length of the swimming pool = 50 meter

Let x be the number of times the swimmer need to swim along pool to cover 200 meter

As we know in 1 time the swimmer can cover 50 meters

⇒ In 2 times the swimmer can cover 2 × 50 = 100 meters

⇒ In x times the swimmer can cover x × 50 = 50x meters

⇒ 50x meters = 200 meters

⇒  x = 200/50 = 4 times

The swimmer need to swim 4 times along pool to cover 200 meters.
