a) 1/7 liters of petrol is used for each mile

Step-by-step explanation:

Justin fills his car with 40 litres of petrol. After travelling 35 miles it's down to 35 litres.

From the above statement:.

The difference is :

40 litres - 35 liters = 5 liters

Hence:

After travelling 35 miles he used 5 liters

(a) How much petrol does the car use each mile?

This is calculated as:

35 miles = 5 Liters

1 mile = x liters

Cross Multiply

35x = 5 Liters

x = 5/35

x = 1/7 liters

Hence, for each mile, 1/7 liters of petrol is used
