Answer:

26.67 km/h

Explanation:

A car travelling 30 km at 40 km/h will reach the destination in 0.75 hours.

Travelling 30 km at 20 km/h takes 1.5 hours.

So in this scenario, the car took 0.75 hours + 1.5 hours = 2.25 hours to travel a total of 60 km. The average speed would be 60/2.25 = 26.67 km/h.
