For queston 1:

Rate of volume change where R is some constant. Since Rate of change is constant it wil have a constant 'gradient' if graphed, and thus we can do rise over run:

at therefore

at therefore

thus

Thus by integrating

at and from before at

Therefore

Can you do the next one on your own? I'll post the answer in 15 minutes.
