A) The time to travel 45 miles at a speed of 40 mph can be found from ...

... time = distance / speed

... time = (45 mi)/(40 mi/h) = 9/8 h = 1 hr 7 min 30 sec

B) The gas consumption can be found from ...

... (45 mi)/(54 mi/gal) = 5/6 gal

C) The cost of gas can be found from ...

... ($3.23/gal)×(5/6 gal) ≈ $2.69
