Question

At the beginning of the week Fayez writes down the mileage of his limo at 2529 at the end of the week the mileage is 2834, Fayez knows he used 75.2 litres of petrol during this week. The handbook states the limo uses 1 gallon of petrol for every 20 miles. Fayez wants to know if his limo uses 1 gallon of petrol for every 20 miles that week. 1 gallon = 4.54 litres . Did his limo use 1 gallon of petrol every 20miles that week. Show your answer clearly

Answer 1

Answer:

No. It used  1 gallon in 18.41 miles.

Step-by-step explanation:

He travelled 2834 - 2529 = 305 miles.

So his consumption is  305 / 75.2 = 4.056 miles/litre.

This equals 4.056*4.54 = 18.41 miles / gallon.

So this is less than the 1 gallon  every 20 miles stated by the handbook.

Answer 2

Answer: His limo used 1 gallon fuel for 18.4136 miles.

Step-by-step explanation:

Fayez covered distance:

2834 - 2529 = 305 miles.

He used fuel = 75.2 litres

75.2/4.54 = 16.5638 gallons petrol used.

His limo covered distance / total petrol used = 305 miles / 16.5638 gallons petrol = 18.4136 miles per gallon.

That is less than 20 miles per gallon
