Hii Namita, here is urr answer.


given:- total distance- 100m

speed of Ajay - 5 m/s
than time taken by Ajay to complete race - distance / speed .
= 100 m÷ 5 m/s
= 20 sec.
but Rahul takes 5 min more to complete race,than
total time taken by rahul- 20+5
= 25 sec.
than, speed of Rahul is - distance / time
- 100m÷ 25 sec= 4 m /s .
