Jeff paddles a canoe 3/5 mile in 1/4 hour. At this rate, how far does Jeff paddle in a half hour? Show all the steps.

He can go 3/5 of a mile in 1/4 of an hour. 1/2 of an hour is twice that of 1/4 of an hour

so all you have to do is double the 3/5

3/5+3/5 = 6/5 or 1 1/5 miles

alternatively you can just multiply by two,

3/5*2/1=6/5 or 1 1/5 miles

This is a proportion problem. I would turn them into decimals to get the best result.

3/5 =.6

1/4 =.25

1/2 =.5

Do the proportion

.6/.25 = x/.5

Cross multiply and divide

.5 x. 6 =.3

.3 divide by. 25 = 1.2

Now turn this into a fraction.

1.2 = 1 2/10

Now simplify

Answer is 1 1/5
