Is there anybody has any idea how I can solve for this. I really need help

Question

Now Ishani and John are ready to use what they know to build the turn indicator. They decide that the signal in their cars goes about once per second. Assuming that they set the trigger to make the indicator go when charge has reached 1 − 1/e of its final value, and that it takes about the same amount of time to discharge as to charge, suggest values for R and C that could be used. (Assume that the capacitor reaches approximately its maximum value, discharges to
1 − 1/e of its maximum value over the course of 1 second, and then begins charging again.)
R=MΩ
C=μF

Answer 1

You Choose any number like 1 for R and another for C like 2.18 and you got your answer
