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 (!)
