Answer:
4.2 × 10⁴ mi
Explanation:
Given data
Average speed: 25 miles per gallon
Fuel: 26.5 gallons
The distance (d) traveled with this amount of fuel is:
26.5 gal × 25 mi/gal = 6.6 × 10² mi
The distance traveled is equal to the difference between the final reading of the odometer and the initial one.
d = final reading - initial reading
initial reading = final reading - d = 43,156 mi - 6.6 × 10² mi = 4.2 × 10⁴ mi
We can estimate that the initial reading of the odometer was around 4.2 × 10⁴ mi.
