2/5 in 1/12 of an hour

x in 1 hour

So multiply 12 to both fractions

2/5 x 12 in 1/12 x 12 of an hour

We get now:

24/5 in 1 hour

or:

4 4/5 in 1 hour

first convert 1/12 of an hour to minutes 1 hr= 60 minutes
1/12 x 60= 5 minutes

ratio and proportion

2/5 / 5= x/60

cross multiply

5x= 24
x= 4 4/5 mi or 4.8 mi
