IF the car is travelling at constant speed during the entire trip, then:
v = speed = distance / time = 90/3 = 30 km/h

assume you're precise, and it really is 30 kilometers in accordance to hour. After the first hour, you'll have travelled 30 kilometers (this is what 30kph means). After the 2d hour, you'll have travelled a extra 30 kms, for a complete of 60 km. After the third hour, you'll have travelled yet another 30 kms, for a grand complete of... ninety kilometers! properly executed!

The car's speed would be 90/3 kph, or 30 kph... what kind of car is this anyway? people sprint faster then that!
