You load boxes onto an empty truck at a constant rate. After 3 hours, there are 100 boxes on the truck. How much longer do you work if you load a total of 120 boxes? Please explain how you got your answer.

Respuesta :

100\3=33.33 Boxes per hour
So we can round it up to 33 because we can only load 33 as we can break the box in .33

120\33=3.6hours
