If the car is traveling at the constant speed of 70 kilometers per hour, then from 3 hours and 30 minutes to 5 hours, the car has been traveling for (5 - 3.5) = 1.5 hours. We can then multiply this total time by the speed of 70 kilometers per hour, which gives 1.5 hours * 70 kilometers/hour = 105 kilometers.
So the car travels 105 km.
