Question

A person drives a car between the two places x and y. On his outward journey he 14. 2
consumes 8 km per liter of petrol, on his return journey he covers 12 km per liter. Find the
average of his mileage assuming the distance between the two places to be 100 kms?​

Answer 1

Heya mate

Set up a proportion to solve. Let x = distance it will cover in 15.5 litres. Then:

(14.75 km) / (1 litre) = (x km) / (15.5 litres)

(14.75)(15.5) = 1x

228.625 = x

It will cover 228.625 km.

Answer 2

Step-by-step explanation:

Solution:

mileage in outward journey = 8 km/liter

mileage in return journey = 12 km/liter

total petrol consumed in outward journey = 100/8 = 12.5 liters

total petrol consumed in return journey = 100/12 = 8.33 liters

total petrol consumed in journey = 12.5 + 8.33 = 20.83 liters

total distance of the journey = 100 + 100 = 200

average of his mileage = 200/20.83 = 9.60 km per liter.
