Answer:
The average speed of the total journey is 70KM/Hr
Step-by-step explanation:
Distance covered in 2 hours at 60kmph = 2×60= 120KM
Distance covered in 2 hours at 80kmph = 2×80= 160KM
Total Distance = 120+160 = 280KM
Total Time = 2+2 = 4 Hours.
AVG Speed = Total Distance/Total Time
= 280 ÷ 4 = 70KMPH
