Quantum CyberTeaser: March/April 1998
B228
Truancy treats. Boris came to school 35 minutes after the first class had
started. So he decided to go to the nearest shop and buy an ice cream cone. Unfortunately,
when he came back, the second class had already begun. He immediately ran for another ice
cream cone and spent as much time at the shop as before. When he returned the second time,
he saw that there were 50 minutes left before the start of the fourth class. Does he have
enough time to buy and eat a third ice cream cone if every class, including the break
after it, takes 55 minutes?
