Solution


Given:
    • Joe’s car can travel 36 miles per gallon of fuel

To find:
    • The number of kilometers the car can travel with 10 liters of fuel

Approach and Working:
    • Joe’s car can travel \(36 * (\frac{8}{5})\) kilometers per gallon of fuel = \(\frac{288}{5}\) kilometers per gallon of fuel
      o This implies that it can travel \((\frac{288}{5})/4\) kilometers per liter of fuel = \((\frac{72}{5})\) km/liter

    • Therefore, it can travel \((\frac{72}{5}) * 10\) kilometers using 10 liters of fuel = 144 kilometers

Hence, the correct answer is Option C

convert liters to gallons

so 10 liter fuel would be = 10/4 = 2.5 gallons of fuel

36 miles per gallons would give 36/5 ;7.2* 8 = 57.6 kms per gallon
mileage would be 57.6*2.5 = 144 liters

E. 160

Solution:

Converting the mileage from mpg to km/L, we have:

36 mi/gal x (8 km / 5 mi) x (1 gal / 4 L) = (36 x 2) km / 5 L = 72 km / 5 L = 14.4 km/L

Therefore, the number of kilometers the car can travel on 10 liters of fuel is 14.4 km/L x 10 L = 144 km.
