The formula for Average speed = $\frac{Total Distance}{Total Time}$

The car travels 80 km in 1 hour.

Then the car travels 90 km in 2 hours.

And finally the car travels 76 km in 1 hour

So the total distance covered by the car = 80 + 90 + 76 = 246 km

The total time taken to cover this distance = 1 + 2 + 1 = 4 hours.

So average speed = $\frac{246}{4}= 61.5$

The average speed of the car is 61.5 km / h
