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?

Ihorangi uses 7.65 litres of petrol to and from work

Step-by-step 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
