Question

One length of a swimming pool is 25m Alison swims 60 lengths of the pool. how many more lengths must Alison swim to complete 1 mile?

hint= 1 mile is 1.6km

Answer 1

4

Explanation:

1 mile = 1.6 km

1 km = 1000 m

1.6 * 1000 = 1600, So to swim 1 mile, she must swim 1600 m

She has already swam 60 lengths which is 1500 m because 60 (the number of lengths)*25 (the length of the pool) = 1500.

1600 (the amount she needs to swim) - 1500 (the amount she has already swam) = 100.

She needs to swim 100 m more, which is 4 lengths because 100/25 = 4.
