Understand Problem: Understanding the problem and identifying the correct formula to use.The problem gives us the formula for calculating the remaining volume of fuel in a car's tank, which is I−E⋅D. Here, I is the initial volume of fuel, E is the fuel efficiency (in cubic centimeters per kilometer), and D is the distance traveled (in kilometers). We need to find the correct calculation that represents the remaining volume of fuel in Carson's tank, in liters, after driving a distance of 120 kilometers with an initial fuel volume of 30 liters and a fuel efficiency of 100 cubic centimeters per kilometer.
Convert Units: Converting the given values to a consistent unit.Since the fuel efficiency is given in cubic centimeters per kilometer, and the initial volume of fuel is in liters, we need to remember that 1 liter =1000 cubic centimeters. This conversion is crucial for maintaining consistency in units throughout the calculation.
Identify Correct Option: Identifying the correct option based on the formula and unit conversion.The formula I−E×D requires us to subtract the product of fuel efficiency (E) and distance (D) from the initial volume of fuel (I). Since E is in cubic centimeters per kilometer and I is in liters, we need to ensure that the units are consistent. Option (A) 30−1000100×120 correctly applies the formula and accounts for the unit conversion by dividing the product of E and D by 1000 to convert cubic centimeters to liters. This is the correct approach to find the remaining volume of fuel in liters.
