A:
Answer:4.2 × 10⁴ miStep-by-step explanation:Given dataAverage speed: 25 miles per gallonFuel: 26.5 gallonsThe distance (d) traveled with this amount of fuel is:26.5 gal × 25 mi/gal = 6.6 × 10² miThe distance traveled is equal to the difference between the final reading of the odometer and the initial one.d = final reading - initial readinginitial reading = final reading - d = 43,156 mi - 6.6 × 10² mi = 4.2 × 10⁴ miWe can estimate that the initial reading of the odometer was around 4.2 × 10⁴ mi.
