Suppose astronauts are in a spaceship moving relative to the Earth at a significant fraction of the speed of light. (a) Do they observe the rate of their clocks to have slowed? (b) What change in the rate of Earth-bound clocks do they see? (c) Does their ship seem to them to shorten? (d) What about the distance between stars that lie along their motion? (e) Do they and Earth-bound observers agree on their velocity relative to the Earth?

would be false hope this out

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
