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.

S/E - represents litres of fuel in 1 hour

E is the economy in km for per litre, so for 1 km it would 1/E litre, so for 60 km - 60/E litres
