Question

A salesman found that he had to travel 45 km each working day in the week (excluding Sundays). At this rate, what would his petrol bill for the 4 weeks be if his car travelled 9 km on 1 litre of petrol, and the petrol cost $1.05 per litre?

Answer 1

Answer:

His petrol bill would be $126.

Step-by-step explanation:

Distance to be travelled by the salesman everyday= 45km

Distance travelled by car in 1 litre of petrol= 9km

Cost of petrol per litre= $1.05

No. of days for which petrol bill is to be found= 4 weeks- 4 Sundays= 28-4= 24 days

Distance travelled in 24 days= 45x24= 1080km

Litres of petrol required to travel 1080km= 1080/9= 120

Petrol bill= 120x1.05= $126

Hence, petrol bill would be $126.
