Final answer:
Isaiah would drive approximately 400 miles on 22 gallons of gas if his vehicle's fuel efficiency is the same as the example given, which is 18.18 miles per gallon (MPG).
Step-by-step explanation:
The student's question is about the relationship between the number of miles driven and the number of gallons of gas used, which is known as the fuel efficiency or miles per gallon (MPG).
To determine how many miles Isaiah would drive on 22 gallons, we need to establish the MPG based on previous data. Since we know from the example that one vehicle drove 400 miles using 22 gallons, we can calculate the MPG by dividing the miles driven by the gallons used:
- Miles Driven = 400 miles
- Gallons Used = 22 gallons
- MPG = Miles Driven / Gallons Used = 400 miles / 22 gallons ≈ 18.18 MPG
Once we have the MPG, we can determine how many miles Isaiah would drive on 22 gallons by multiplying the MPG by the number of gallons:
- Miles Driven on 22 Gallons = MPG * Gallons = 18.18 MPG * 22 gallons = 400 miles
Therefore, if Isaiah's vehicle has the same MPG as the example, he would drive 400 miles on 22 gallons.
