Answer 2

Answer:

Average speed= 14.63m/s

Explanation:

D1=50m,

V1=50m/s,

And D2=100m,

V2=10m/s,

Now;Speed =Distance /Time

So,Time =Distance/Speed

So, t1=50/50

So, t1= 1 second.

And, t2=100/10

So, t2= 10 second.

Now,

Average speed = Total Path Length/Total Time

So, Average Speed= (50+100)/(10+1)

Average Speed= 150/11

So, Average speed=14.63m/s
