Question

A car travels 13 km 500 m in an hour and consumes 1 L of petrol for every 6 km.
(i) How much distance will it travel in 8 hours ?
(ii) How much petrol will it consume?​

Answer 1

Answer:

d = 13+0.5 = 13.5 km

t = 1h

s = 13.5/1 = 13.5 km/h

i) when t = 8h

d = s×t

= 13.5 × 8

= 108 km

ii) 6 km = 1L

1 km = 1/6 L

108km = 108/6

= 18 L
