Question about which route would use more petrol/fuel?

Question

and by how much.

Im deciding on a hospital to have my baby.

Hospital A is 25 minutes away and approx 25km's going suburban/back streets.

Hospital B is 35 minutes away and approx 50km's going down the highway.

Hospital B is preferred hospital.

Does high ways use less fuel than back streets? Would hospital B cost much more in travel?

Thanks (ill have to do frequent pre-birth trips there not just the one off)

Answer 1

You're having a baby. WHO CARES if the better hospital is 10 minutes farther away.  Do what's best for the baby (and the mom)

Answer 2

If there was no preferred hospital, take the back streets.  A highway drive, I imagine it's difficult to pull over in case you have to stop suddenly.  

The difference is 10 minutes, a woman in labor, and an excited driver.  I would not want to think of the risk of accident on a fast road, the impact speed.  But since you have the hospital you want, take the highway, because at a certain speed, your car conserves gas.
