The cat, the coffee and the cake
Ten minutes before putting the cake in the oven, I put my cat outside the house.
The cake should cook for 35 minutes, so I set the alarm clock to ring at 35 minutes after placing the cake in the oven. I immediately made myself a coffee, which took me 6 minutes.
Three minutes before the coffee was finished drinking the cat came into the house. That was 5 minutes before the alarm went off.
The phone rang in the middle of the time I had just made coffee and the cat come home. I spoke on the phone for 5 minutes and hung up. It was 3:59 in the afternoon.
What time did I get the cat out of the house?
