Answer 2

Answer: 3 11/20 sec

Step-by-step explanation:

Ashok's time= 18 1/5 sec

Sumit's time= 21 3/4 sec

Difference between both= Sumit's time - Ashok's time

                                        = 21 3/4-18 1/5

                                        = 3 11/20 sec

Therefore, Sumit took 3 11/20 more seconds to run 100m than Ashok.
