Roughly how much would a 55 mile trip by car take?

The car I have is a Ford fiesta 2011

At what speed, skippy? If you were driving 55 MPH them it would take exact one hour. Tracking?

The 2017 Fiesta 2400 cc 4 cyl, 5 door, 6 speed auto I rented Averaged 29 MPG. I guess it got 40 on the freeway, steady, at 55 MPH.About $3.23 for gas, Only, at $2.35 /gal regular.
Of course, insurance, registration, wear and tear must also be factored in. At $58 month ins. And $24 year reg, that's 26 cents. If your tires wear out in 50K, at $250 a set, that's 28 cents. Not including tune ups, parts, tire mounting/balancing, smog.

So, realistic total is.$3.77.

EDIT: 38 MPG, 6 speed auto: https://www.fueleconomy.gov/feg/bymodel/2011_Ford_Fiesta.shtml

How much what? Time? Gas? Money? 55 miles is an hour or less away. It isn't hard to figure out.

Depends on how fast you are going. I.e. If you were driving 55mph the trip would take an hour

Around 1 hour at highway speed.

2.3 gallons

If you go 60 miles per hour you would get there in 55 minutes.

That depends how many stop signs there are and how fast you drive.

Two walnuts and a banana.

How much WHAT?
Time?
Fuel?
Something else?
