Answer:

The charge of a current in a given period of time is calculated by multiplying the current and the duration of that current. Since in the problem charge would be constant, we can relate the first conditions to the second conditions.

q = IT

q1 = q2

I1T1 = I2T2

8.4(240)=(10.5)(T2)

T2 = 192 seconds
