We calculate current from the formula:
\(I= \frac{q}{t}\) , where q is a electric charge transferred over time t 
Time should be converted to seconds:
1h 15 min= 75min= 4500s
I=\(\frac{90C}{4500s}=0,02A\) Result is in unit-Ampere

Current = C / seconds.

1 hour = 3600 seconds
15 minutes = 900 seconds

1 hour 15 minutes = 4500 seconds

90 C / 4500 sec = 0.02 amperes = 20 milliamperes
