The Quasi JX is a new car model. Under ideal driving conditions, the Quasi Jx’s fuel economy is E kilometers per liter (E \(\frac{km}{L}\)) when its driving speed is constant at S kilometers per hour (S \(\frac{km}{h}\)).
In terms of the variables S and E, select the expression that represents the number of liters of fuel used in 1 hour of driving under ideal driving conditions at a constant speed S, and select the expression that represents the number of liters of fuel used in a 60 km drive under ideal driving conditions at a constant speed S. Make only two selections, one in each column.

fuel efficiency or mileage is basically: distance traveled / no. of liters. (km/L)
Hence, No. of liters = Distance traveled / fuel efficiency (mileage)
Liters of fuel consumed in 1 hour = speed * 1 / mileage = S / E
Liters of fuel consumed in 60 km = Distance / mileage = 60 / E
Hence, No. of liters = Distance traveled / fuel efficiency (mileage)
Liters of fuel consumed in 1 hour = speed * 1 / mileage = S / E
Liters of fuel consumed in 60 km = Distance / mileage = 60 / E
