If two different sized objects have the same density, what can you conclude about the object?

Short YES

Long

Density is generally regardless of how big or small a substance is and is neither dependant on its shape. A statue made of gold and a brick made of gold might have different masses and volume but they have same density.

By universal definition, density of a substance is the mass per unit volume.

D = Mass/Volume

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
