Hey Friend,

Question: A girl moves with the speed of 3 kilometre per hour for 1 hour and 2 km per hour for another 1 hour now find the average speed of the girl and the total distance covered by her
Solution:
Average speed = total distance covered/ total time taken
Total distance covered= distance covered in first one hour + distance covered in second one hour
Total time taken = 1 +1=2 hours
Distance= speed x time
Distance covered in first one hour = 3x1 =3km
Distance covered in second one hour = 2 x 1 = 2km
Total distance covered = 3 + 2 = 5 km
Average speed = 5/2 = 2.5 km/h

avg speed=total distance/total time=5km/2hr=2.5km/h
distance=speed×time
=2+3 km=5km
distance=speed×time
=2+3 km=5km
