Swimming pool yard

Question

A swimmer has been using a pool with a 50 yard length. How many lengths would the swimmer need to do in the 25 m length pool to equal 10 lengths in the 50 yard pool? (1 yard = 0.9144 metres)

Answer 1

10 lengths x 50 yds/1 length x 0.9144m/1 yd x 1 length/25m = 18.288 lengths

Answer 2

Hi, Mercy!

 

Okay, so we need to do some conversions here. 

We need to find out  how many 25 meters are in 10 x 50 yards.

So 10 x 50 yards = 500 yards.

So now we need to find how many 25 meters are in 500 yards.

Let's convert 500 yards to meters:

500 x .9144 = 457.2 meters

So our equation is: 

457.2 ÷ 25 = 18.28 lengths
