Answer: The answer is 20 seconds!
Step-by-step explanation:
Since X has given Y a head start of 25m, Y will run 75m only! Yet, X wins by 5 secs.
Therefore, time for Y is t+5, X is t.
From second Condition, head start is 50 and ends in dead heat means they end up in same time i.e same speed!
75/(t+5) = 50/t by equating with same speed
Solving, t =10sec.
Therefore X can go 10m/s (100m/10sec)
For 200m, 20 secs!
