Math help please..?

Question

Glenn paddles his canoe down the Concord River at a rate of of 6 miles per hour. When he rests and drifts along, he travels 3 miles per hour. How long will it take Glenn to travel from Newtown to Larabee, a distance of 45 miles, if he paddles for an hour and rest for an hour? Explain how you determined the time. Also rewrite the problem in your own words.

Answer 1

He travels 6 miles per hour paddling.
He travels 3 miles per hour doing nothing.

So, every two hours, he goes 9 miles...or 4.5 miles per hour.

rate x time = distance.

4.5 mph x time = 45 miles

45 miles / 4.5 mph = 10 hrs.

It will take him 10 hrs.

Problem rewritten:

Glenn travels along a river at a rate of 9 miles every two hours. How long will it take him to travel the 45 miles from Newtown to Larabee?

Answer 2

I think the question is very simply stated as it is.
I just wrote out:

6 + 3 + 6 + 3 + 6 + 3 etc until the sum was 45.

Therefore: 6 + 3 + 6 + 3 + 6 + 3 + 6 + 3 + 6 + 3 = 45
It takes 10 hours.
