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
