Question

A bike covers 42 km in one litre of petrol.
a) Find the distance covered by the bike IN 2 1/7
litres.

b) Find the quantity of petrol required to cover 140 km.

Answer 1

Answer:

a) 90 km b) 3 1/3 litres

Step-by-step explanation:

distance covered with one litre = 42 km

a) amount of petrol = 2 1/7 litres = 15/7 litres

distance covered with 15/7 litre = 42 *(15/7)

= 6 *15 = 90 km

b) amount of petrol for one km distance = 1/42 litres

amount of petrol for 140 km distance = 1/42 * 140

= 10/3 = 3 1/3 litres
