Question

E
1. (a) A school bus company charges $2.70 per kilometre to ferry 36 children for
an outing. How much does each child have to pay if the distance travelled
for the trip is 32.5 km?
(b) A car requires 25 litres of petrol to travel a distance of 265 km. Find
the distance that the car can travel on 58 litres of petrol,
(ii) the amount that the car owner has to pay to travel a distance of 1007 km
if a litre of petrol costs $1.95. (with solution)​

Answer 1

Answer:

a 2.70*32.5

87.75

so each child will pay  rupees 87.5 for the outing

b  265 divided by 25

10.6

so the car can travel 10.6 km in one litre of petrol

and so using 58 litres of petrol it can cover a distance of

58*10.6

614.8 km

ii)  so using one litre he can cover 10.6 km

so to cover 1007 km he needs

1007   ÷   10.6 =

95

so he needs 95 litres of petrol

and with the price of 1.95 dollars

the cost will be 95*1.95

195.25

hope it helps
