Ответ:
when jerome paddle in flowing river towards east the net speed of jerome will increase
so the net speed of jerome will be given as
now the speed of paul will be same as it is given as he is running on the ground
so
so here we can say since the speed of jerome is more so he will win the race
now as we know the distance so the time difference is given as
so jerome will reach first and the time difference will be 203.55 s or 3.4 min
