Answer:
Average speed= 40 km/ hr
Explanation:
The bus had already reached 100 at 10:30, the beginning time.
Thus, the actual distance travelled during the given duration will be 220- 100 = 120.
From 10:30 to 11:30, It is 1 hour.
From 11:30 to 1:30, It is 2 hours.
Average speed= (Total Distance travelled)/(Total time taken)
= 120 km/ 1+2 hr
= 120 km / 3 hr
= 40 km/hr
