If rachel swims 120 miles in 60 seconds (i minute), how many minutes will it take her to swim 1/2 mile?

SOLUTION:

120 miles = 60 seconds

120 ÷ 240 = 60 ÷ 240

120 × 1 / 240 = 60 × 1 / 240

120 / 240 miles = 60 / 240 seconds

1 / 2 mile = 1 / 4 seconds

1 / 2 mile = 1 / 4 ÷ 60

1 / 2 mile = 1 / 4 × 1 / 60

1 / 2 mile = 1 / 240 minute

FINAL ANSWER:

Therefore, it will take Rachel 1 / 240 of a minute to swim a 1 / 2 mile.

Hope this helps! :)
Have a lovely day! <3
