Newton’s second law of motion states that an object’s acceleration is equal to
A. the net force on an object divided by its mass.
B. the mass of an object divided by its net force.
C. The net force of an object divided by its speed.
D. the speed of an object divided by its net force.

i think the answer would be b

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

the answer to this is proletariats.

hope this : )
