Answer:
The driving time at 54 miles per hour is 37.04 hours.
The driving time is at 75 miles per hour is 26.67 hours.
The gasoline cost at 54 miles per hour is $201.82
The gasoline cost at 75 miles per hour is $302.73
Step-by-step explanation:
Suppose your car averages 33 miles per gallon on the highway if your average speed is 54 miles per hour,
and it averages 22 miles per gallon on the highway if your average speed is 75 miles per hour.
The driving time for a 2000-mile trip if you drive at an average speed of 54 miles per hour = Distance / Speed = 2000 / 54 = 37.04 hours.
The driving time for a 2000-mile trip if you drive at an average speed of 75 miles per hour = Distance / Speed = 2000 / 75 = 26.67 hours.
Assume a gasoline price of $3.33 per gallon.
The gasoline cost for a 2000-mile trip if you drive at an average speed of 54 miles per hour = (Distance / Gas mileage) * Cost = (2000/33)*3.33 = $201.82
The gasoline cost for a 2000-mile trip if you drive at an average speed of 75 miles per hour = (Distance / Gas mileage) * Cost = (2000/22)*3.33 = $302.73
