Question

An object travel 16m in 4s and the 15m in 2s.What is average speed of the object

Answer 1

Explanation:

Let the speed of object at both instances be x and y

Average velocity=(x+y)/2

Speed=Distance/Time

FOR X

x=16/4

x=4m/s

FOR Y

y=15/2

y=7.5m/s

Now avg velocity=(x+y)/2

(4+7.5)/2

=11.5/2

So

average velocity of object is 11.5/2 m/s
