By converting the unit, the gas needed to complete a 142 km trip is 11.15 liters.
We need to know how to convert from mile and gallon to km and liter units to solve this problem. The conversions unit is
1 mile = 1.60934 km
1 gal = 4.54609 liter
From the question above, we know that:
gas mileage = 36 mi / gal
distance = 142 km
Convert the gas mileage to km/l
gas mileage = 36 mi / gal
gas mileage = 36 x 1,60934/4.54609 km/l
gas mileage = 12.74 km/l
Find the required gas
required gas = distance / gas mileage
required gas = 142 / 12.74
required gas = 11.15 liters
Hence, the gas needed to complete a 142 km trip is 11.15 liters.
