Question

An object travels 18m in 4s and next 18m in 2s. Calculate the average speed of the object

Answer 1

1st situation
distance = 18m
time taken = 4 sec
2nd situation
distance= 18m
time= 2 sec

total distance = 18+18
36m
total time = 4+2
: 6sec

average speed = total distance / total time taken
average speed = 36m/6sec
6m/sec

Answer 2

Average Speed :-
Distance covered by the object / Total Time taken

Total Distance covered = 18m + 18m = 36m
Total Time Taken = 4s + 2s = 6s

Therefore , Average Speed= 36m/6s = 6m/sec
