A motorcycle can travel 70 miles per gallon. Approximately how many gallons of fuel will the motorcycle need to travel 60 km?
kap26 [50]

Answer:

We have the following given

mileage = 70 miles per gallon

distance = 60 km


Required: amount of fuel in gallons


First, we must convert the distance to miles, so

60 km (1 mi/1.6 km) = 37.5 mi


So, the amount of fuel is

37.5 mi / (70 mi/gal) = 0.54 gallon
