Question
A car covered first 150 km distance in 6 liters petrol, next 70 km distance in 3 liters patrol and next 130 km distance in 8 liter. What is the average mileage of the car in the whole journey?
Solution
To calculate the average mileage of the car for the whole journey, we need to follow these steps:
-
First, we need to find out the total distance covered by the car. This is done by adding all the distances together. So, 150 km + 70 km + 130 km = 350 km.
-
Next, we need to find out the total amount of petrol consumed by the car. This is done by adding all the petrol amounts together. So, 6 liters + 3 liters + 8 liters = 17 liters.
-
Finally, we calculate the average mileage by dividing the total distance by the total petrol consumption. So, 350 km / 17 liters = approximately 20.59 km/liter.
So, the average mileage of the car for the whole journey is approximately 20.59 km/liter.
