I know that V(t=0) is 20 and time = 1 and capacitance = .1
what I'm having trouble is finding V(t=1) to find dV/dt. Can someone help me?

Any work that you've tried and/or relevant equations you could use?

Yeah relevant equations are

And I'm not asking for the answer. More of if someone can explain to me how to find voltage at time = 1

Okay right now you have a differential equation. Can you follow Kirchoff's Voltage Law to determine what that is going to be? I'm not sure at what level you are academically, so I'm not sure if the derivation would be the correct path to go down...
