If m is the number of miles per gallon a car gets, and l is the number of liters it takes to go 100 km, find a mathematical equation that lets you convert m to l.

We will apply the conversion factors to find the final equivalence. We will start by converting the values of gallons per mile to kilometers per liter. Later we will convert the total liters into the 100 kilometers given and find the final ratio:

Convert miles per gallon (MPG) to kilometers per liter

Here 0.421km/L implies that .421km with 1 L of fuel, then

Therefore

Therefore the mathematical equation that convert M to L is 1M = 238L

heat the gas and measure the pressure

the total distance traveled by the car is

30km + 49km = 79 km .
