A motorcycle can go 50 miles using one gallon of gas. About how many gallons of gas will be used to go 150 kilometers? (Hint: 1 mile is approximately 1.6 kilometers)

The answer to your question is 1.875 gallons

Step-by-step explanation:

Data

distance = 50 mi

volume of gas = 1 gal

volume for 150 km = ?

Process

1.- Convert 50 mi into kilometers

                         1 mile 1.6 km

                          x         150 km

                          x = (150 x 1)/1.6

                          x = 93.75 mi

2.- Calculate the gallons wasted

                          1 gallon 50 mi

                          x             93.75 mi

                          x = (93.75 x 1)/50

                          x = 93.75/50

                         x = 1.875 gallons
