Time taken by Ravi = 2 hrs 10 mins 
                                = 2*60+10
                                = 130 minutes
                                = 130*60
                                = 7800 seconds
Time taken by Sham = 6200 seconds
Time taken by Ravi > Time taken by Sham

More time taken by Ravi =  7800 - 6200
                                        = 1600 seconds
                                        = 1600/60
                                        = 160/6
                                        = 80/3
                                        = 26.67 minutes

Ravi has taken more time than Sham by 1600 seconds or 26.67 minutes
