At exactly the same time Daisy and David both step off a diving platform 5 m high. David jumps off and out from the platform whereas Daisy just takes a step from a standing position. Who will reach the water first?

none of them

Explanation:

the horizontal speed doesn't matter and if i got it right both of them started from the same height and both of them fell to the water (none of the jumped *higher only farther) and that's the only thing that matters. so they'll both end up there at the same time cause only gravity is affecting their movement process among the way.

1 the 4 is sig

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
