A major part of the greenhouse effect is that it involves the absorption of the earth's outgoing radiation by atmospheric gases. Along with carbon dioxide, the atmospheric component that is largely responsible for this process is the water vapor.

Water vapor is already the gaseous phase of water.  It evaporates all the way through the atmosphere. Since water vapor is produced from the boiling liquid of water, or from the ice sublimation, all the radiation and other chemicals that produces greenhouse gases which are present in the water will also be carried towards the Earth’s atmosphere during the process of evaporation. This, along with carbon dioxide totally damages the Earth’s ozone layer.

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
