Question

Ihorangi travels 51 km to work and 51 km from work each day.

Ihorangi drives a car with a fuel consumption of 7.5 L/100 km to and from work each week.
How many litres of petrol does Ihorangi use travelling to and from work?

Answer 1

Ihorangi uses 7.65 litres of petrol to and from work

Explanation:

If the car Ihorangi drives consumes 7.5 L/100 km

Then for 1 km journey, the car will consume 7.5/100 L

= 0.075 L

If Ihorangi travels 51 km to work and 51 km from work

Therefore Ihorangi travel (51 + 51) km daily to and from work

= 102 km daily

The fuel he consumes daily is 102*0.075 L

= 7.65 L
