Answer:
3 1/3 hours
Explanation:
We need to do 2/3 * 5 because it is five times as many.
Then we convert 5 to 5/1 because it is the same value and easier to understand.
Now we multiply across (little minus sign is fraction bar for lack of a better way to right it):
2 * 5 10 1
- - = - = 3 -
3 * 1 3 3
So 3 1/3 hours is the answer!
