Answer:

The average speed of car is 67 kilometers per hour.

Explanation:

Given that:

Distance travelled in one hour = 45 km

Distance travelled in next 2 hours = 78*2 = 156 km

Total distance = 45+156 = 201

Total time = 1+2 = 3 hours

Average speed of the car =
$(Total\ distance)/(Total\ time)$

Average speed of the car =
(201)/(3)

Average speed of the car = 67 km/hr

Hence,

The average speed of car is 67 kilometers per hour.
