speed= distance/time
distance covered in first hour
20 km
distance covered in next two hours
120 km
total distance covered= 140 km
average speed= total distance covered by object / total time taken to cover the distance
total time taken to cover the distance = 3 hours
hence the average speed is 140/3=46.67 kmph

average speed= total distance travelled / total time taken
average speed = 20 + 60 /3 hrs
= 80 / 3= 26.67 (approx)
average speed = 20 + 60 /3 hrs
