Given,
A truck travels 60 km in the first hour and 80 km in the second hour.
To Find,
The average speed of the truck.
Solution,
The formula for calculating the average speed is
Average speed = Total distance/Total Time
In this question,
Total distance = 60+80 = 140 km
Total time = 1+1 = 2 hours
So,
Average speed = 140/2
Average speed = 70 km/hr
Hence, the average speed of the truck is 70 km/hr.
