Question

In a car there is 50 litres of petrol. It uses 25% of the petrol in one trip. How much petrol is left in the car after 2 trips?

Answer 1

car efficiency = 80km/ 4L = 20 km/L

“The car will go 20 km for every liter.”

Distance traveled = (car efficiency * petrol used)

Then for 25 liters:

(20 km/L)(25 L) = 500 km

Answer 2

100%is 50 litere and find the 25%

so let the 50% of 50 liters is 25

now the 12.50 litere are used in one trip

so 12.50 ×2 = 25 litere this is the petrol is used in 2 trips is 25 literes are 50% of total petrol

so 100% is 50 and 50% is 25 literes are left in car
