Zorluk: OrtaFuel Efficiency and Range

An interstate bus travels from a central terminal to a destination city 150150 miles away and immediately returns along the same route. The bus averages a fuel efficiency of 1212 miles per gallon. If the bus starts the journey with exactly 6060 gallons of fuel, how many gallons of fuel will remain in the tank at the end of the round trip?

  1. A
    25
  2. 35Cevap
  3. C
    47.5
  4. D
    57.5

Cevap

There will be 35 gallons of fuel remaining in the tank.
The correct answer is derived by first finding the total round-trip distance, which is 150×2=300150 \times 2 = 300 miles. Dividing this distance by the fuel efficiency of 1212 miles per gallon gives the total fuel consumed: 300÷12=25300 \div 12 = 25 gallons. Finally, subtracting the consumed fuel from the initial 6060 gallons yields the remaining amount: 60−25=3560 - 25 = 35 gallons.

Adım Adım Çözüm

1
Calculate the total distance for the round trip.
150 miles * 2 = 300 miles
The bus travels to the destination and returns, meaning the one-way distance must be doubled.
2
Determine the total fuel consumed during the entire trip.
300 miles / 12 miles per gallon = 25 gallons
Dividing the total distance by the fuel efficiency gives the total amount of fuel required.
3
Calculate the remaining fuel in the tank.
60 gallons - 25 gallons = 35 gallons
Subtracting the consumed fuel from the initial fuel amount provides the remaining balance.

Anahtar Kavram

Calculating remaining fuel by finding the total round-trip distance, dividing by fuel efficiency to find consumed fuel, and subtracting from initial capacity.
