Explanation:
Distance between Delhi to jaypur
= 250 km
Time taken in going Jaypur = 5 hours
Then speed of bus while going to jaypur = 250/5
= 50 km/h
Now,
Time taken in coming from Jaipur
= 4 hours
So
Speed of the bus while coming from Jaipur = 250/4
= = 62.5 km/h
Now,
Average velocity = total distance covered/total time taken
Total distance covered = 250 × 2
= 500 km
Total time taken = 5 + 4
= 9 h
Average velocity = 500/9
= 55.5 km/h

Answer:
dehi to jaipur journey
distance= 250 km
time= 5h
speed= distance/time
50km/h
jaipur to delhi journey
time= 4h
distance= 250 km
speed = distance/time
250/4 = 62.5km/h
AVERAGE SPEED = sum of two speeds/2
112.5/2
56.25 km/h
