A baseball player throws a baseball at 42 m/s. If the other player catching the baseball is 18 m from the player, how much time does it take the baseball to reach him?

Divide the distance by the speed:

(18 m) / (42 m/s) = 3/7 s ≈ 0.43 s

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
