            The solution by @Penguin is incorrect.

            I came to give you  INSTRUCTIONS  on how to solve the problem  PROPERLY.



You should substitute time in  MINUTES  to the formula.

So,  substitute   t= 90 minutes.


Surely,  I will not do it for you --- such simple and routine things every student  MUST  DO  ON  HIS  (or her)  own.


Happy calculations (!)
