Answer
Time taken by car = 1.07 hours = 1 hour 4.2 min = 64.2 min
Gasoline consumed = 2.49 gallons
Work Step by Step
1 mi/hr = 1.61 km/hr
Thus 65 mi/hr = 104.65 km/hr
Since speed = $\frac{Distance}{Time}$,
Thus Time = $\frac{Distance}{Speed}$,
$\frac{Distance}{Speed}$ = $\frac{112}{104.65}$ = 1.07 hours
Time = 1.07 hours = 64.2 minutes.
For gasoline,
1 mile= 1.61 km
Thus, 28 miles = 45.08 km.
Thus, 45.08 km takes up one gallon of gasoline.
Thus 112 km will take 2.48447 $\approx$ 2.49 gallons of gasoline.
