Question

Lynn Matthews wants to swim 1km in a 50-m-long pool. How many pool lengths must she swim?

show work please thank you!!!!

Answer 1

There are 1000m in 1km.

1000m / 50m

= 20

She needs to swim 20 pool lengths.

Answer 2

1 km = 1000 m. The pool is 50 m long. So she must swim 20 (that's 1000 ÷ 50) lengths to reach 1 km.

Answer 3

First one needs to convert km to m. 1km = 1000m

then one needs to divide 1000 by 50
