Question

John needs 13 bottles of water from the store. john can only carry 3 at a time. what's the minimum number of trips john needs to make to the store?

Answer 1

The minimum amount of trips would be 5. This is because in one trip he can only carry 3, so you would take 5 times 3. You may think it should be 4 trips, but 12 is 1 short of 13,so you would have to make one extra trip to get all 13 bottles.
