Answer 2

`(11)/(8)`
`\text{gallons}`

Explanation:

Given: In
`1(1)/(2)` hour, a lawnmower uses
`2(1)/(16)` gallon of fuel.

To Find: How many gallons of fuel did the lawnmower use each hour.

Solution:

Number of hour lawnmower used
`=1(1)/(2)`
`\text{hour}`

`(3)/(2)`
`\text{hour}`

Fuel consumed by lawnmower
`=2(1)/(16)`
`\text{gallon}`

`(33)/(16)`
`\text{gallon}`

Fuel used by lawnmower each hour
`=\frac{\text{Total fuel used}}{\text{Total time taken}}`

`=((33)/(16))/((3)/(2))`

`=(11)/(8)`
`\text{gallon}`

Hence the fuel consumed by lawnmower each hour is
`=(11)/(8)`
`\text{gallon}`
