Capacitance Derviation mystery

Hello, there Physics enthusiants just want to ask question about Capacitanceso we know that C=Q/V and when know that V=IR and I=Q/t therefore Q=It so can you combined the equations to get I*t/I*R and cancel out current to get t/R? please clarify this will do me plenty and also because i tried google nothing useful has came out .Anyways thanks for reading
