Answer 2

Answer:

$\frac{11}{8}$ $\text{gallons}$

Step-by-step explanation:

Given: In $1\frac{1}{2}$ hour, a lawnmower uses $2\frac{1}{16}$ gallon of fuel.

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

Solution:

Number of hour lawnmower used $=1\frac{1}{2}$ $\text{hour}$

                                                         $\frac{3}{2}$ $\text{hour}$

Fuel consumed by lawnmower   $=2\frac{1}{16}$ $\text{gallon}$

                                                      $\frac{33}{16}$ $\text{gallon}$

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

                                                            $=\frac{\frac{33}{16}}{\frac{3}{2}}$

                                                            $=\frac{11}{8}$ $\text{gallon}$

Hence the fuel consumed by lawnmower each hour is $=\frac{11}{8}$ $\text{gallon}$
