Answer:
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
To calculate the total petrol cost, we convert the trip distance to miles, determine the gallons needed, and then convert this to liters. The total cost is obtained by multiplying the number of liters by the price per liter, resulting in RM28.45.
The question involves calculating the total petrol cost for Brendan Gan to drive from Johor Bahru to Kuala Lumpur. Given that the distance is 330 km and his car's fuel consumption is 60 miles per gallon, we need to carry out several conversions and calculations to determine the cost.
First, we convert the distance from km to miles:
330 km imes (1 mile / 1.61 km) = 205.0 miles.
Next, we calculate the gallons of petrol needed:
205.0 miles / 60 miles per gallon = 3.417 gallons.
Now, we convert gallons to liters:
3.417 gallons imes 4.5 liters per gallon = 15.377 liters.
Finally, we calculate the total cost:
15.377 liters imes RM1.85 per liter = RM28.45 (rounded to two decimal places).
