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?a20.6b22.4c24.5d26.8
Solution
To find the average mileage of the car for the whole journey, we first need to find the total distance covered and the total amount of petrol used.
- Total distance covered = 150 km + 70 km + 130 km = 350 km
- Total petrol used = 6 liters + 3 liters + 8 liters = 17 liters
Mileage is calculated as the distance covered per unit of fuel used. So, the average mileage for the whole journey would be the total distance covered divided by the total petrol used.
Average mileage = Total distance / Total petrol = 350 km / 17 liters = 20.6 km/liter
So, the average mileage of the car for the whole journey is 20.6 km/liter. Therefore, the answer is (a) 20.6.
