It would depend on the car, what damage it sustains and how much it will cost to fix, compared to how much the car is worth. For example, in the early 90's, brand new Chevy Sprints, still on the dealer's car lot, would be considered totalled if the windshields were broken by vandals. This was because it actually cost more to replace the windshield, than it did to replace the entire car.
Note for Britons: 'To total' in the USA means 'to write off' in the UK.
10 to 20 mph
We know that the time traveled is 5 hours, since a car going 10 mph faster travels an extra 50 miles over the same amount of time.Dividing 300 miles by 5 hours, we get 60 mph. Since the car is traveling 10 mph, the car is traveling 70 mph.

10 mph
a = (vf - v0)/Δt 10 mph/s = (45 mph - 20 mph)/Δt Δt = 2.5 s
One car length for every 10 mph.
Car 1 and 2 travel create a 110 miles gap between each other per hour because car 1 is doing 60 mph and car 2 is doing 50 mph for a total of 110 miles. In three hours they will be 330 miles apart.
One car length for every 10 mph.
divide mph by 10, and then multiply answer by 6 will give you kilometers
About 10 seconds.
