You need to know the distance between the two cities, to use the formula distance = velocity * time from which you solve time = distance / velocity.

That distance is 127.0 miles (for one of the routes)

So, you have time = 127.0 miles / 55 miles/hour = 2.3 hours

That is about 2 hours and 18.5 minutes.

Answer: 2.3 hours
