Question

b) A car can travel 240 km in 15 L of petrol.
(i) How much distance can it cover with 25 L of petrol?
(ii) How many litres of petrol will be required to cover 160 km?​

Answer 1

Step-by-step explanation:

# Distance and litres of petrol are in direct proportion.

Let x = distance, y = litres of pertrol

k = x/y

k = 240/15 = 16 = x/y

x = 16y.

i) y = 25 L

x = 16 * 25

  = 400 km

ii) x = 160 km

160 = 16y

y = 160/16

y = 10 L.

Regards!

Answer 2

Answer:

In 25 liter of petrol we can cover 400 km
