Question

Sam drinks water at an incredible rate. She drinks 2 1/5 liters of water every 3/4 of an hour. Sam drinks water at a constant rate. About how much water does Sam drink per hour?

Answer 1

2.9 litres

or

2 14/15 litres

Explanation:

To determine the amount of water Sam drinks in an hour, divide the total amount drunk by the number of hours

Amount drank in an hour = total litres drunk / time

`2(1)/(5)` ÷
`(3)/(4)`

`(11)/(5)` ×
`(4)/(3)` =
`(44)/(15)` = 2
`(14)/(15)` litres
