Brendan Gan is about to drive to Kuala Lumpur from Johor Bahru. The distance from Johor Bahru to Kuala Lumpur is 330 km. Brendan's car can drive 60 miles using 1 gallon of petrol The current petrol costs are RM1.85 per liter. Calculate the total petrol cost for Brendan to drive from Johor Bahru to Kuala Lumpur.
Use: 1 gallon = 4.5 liters
1 mile = 1.61 km
Round up answer to 2 decimal places (8 marks)

The total cost in petrol will be: RM 28.43

Explanation:

The distance to be covered is: 330 km

The car does 60 mi per 1 gallon

so we convert this into km per liter as

60 mi/gal = 60 * 1.61 / 4.5 = 21.47 km/liter

Then, if 1 liter is needed to cover 21.47 km, then to cover 330 km one would need:

330 / 21.47 liters = 15.37 liters

Since each liter costs RM 1.85, then the cost in gas will be:

1.85 * 15.37 = RM 28.43
