 PRICE PER LITRE
HOW MANY LITRES?( QUANTITY OF PETROL)
PRICE: NUMBER OF LITRES × PRICE / litre
ANSWERS
1. On High Ways: ; Therefore, uses = 36 litres;
At 60 km/h: ; Therefore, uses = 7,5 litres
At 90 km/h: Rest = 540 – 324 – 90 = 126 km.; Therefore, uses = 12,6 litres
Cost of (36 + 7,5 + 12,6)l of petrol = R2.10 x 56,1 = R117,81
