Jim ran 12 1/2 miles in 2 1/2 hours. How many hours for 1 mile?
Klio2033 [76]

Answer:

1/5 hours i.e 0.2 hours (which is 12 mins)

To work out how many hours it takes hime to drive one mile, we divide the number of hours (2.5) by the number of miles (12.5),

i.e 2.5 ÷ 12.5

which equals 1/5 = 0.2 hours (= 12 mins).
