Answer 1

Answer:

24m/s

Explanation:

Let the body goes from A to B in the t1 sec and comes back let the distance between A to B be sec .

• t1 = s/20
• And t2 = s/30
• Total distance travelled = sec + sec = 2sec
• Total time taken = t1 + t2
• = sec/20 + sec/30 = 5sec/60
• Average velocity = 2sec /t1 + t2
• putting the values ,we get average speed =24m/s.

so , this answer is helpful for us
