Answer:
0.96 g/cm3, and it will float!
Explanation:
I've explained how to do this before (remember me? lol), but ig I'll do it again..
By looking at the graph you can see that Object C has a mass of ~24 grams and a volume of ~25 cm3
Density = Mass/Volume -> 24 grams/25 cm3 = 0.96 g/cm3
Density of water is 1 g/cm3
Object C is less dense than water and therefore will float (just barely, though)

To work out the time taken to travel a certain distance a ta certain speed, we divide the distance by the speed.
So, 3/5 = 0.6 hours. To convert this to minutes, we need to work out 0.6 of 60. We can do this by simply multiplying 0.6 by 60, to get 36 minutes.
Hope I helped! xx
