Answer 2

Answer:

3/4 mins

Step-by-step explanation:

time taken by ravish = 2 1/2 mins

5/2 mins = 5/2 * 60 = 150 secs

time taken by Rahul = 7/4 mins = 7/4 * 60

= 105 secs

150 > 105

Rahul takes less time than ravish

difference in time = 150 - 105 = 45 secs

required fraction = 45/60 = 3/4 mins
