Forgotten WatchMath brain teasers require computations to solve.
Mr. Greenwich and his wife were shopping when they decided to go their separate ways to speed things up. They agreed to meet at the bank at 2:00 p.m. Mr. Greenwich realized several minutes later that he had forgotten his watch. He asked a lady walking by for the correct time. Her watch was five minutes fast, but she thought it was ten minutes slow. Mrs. Greenwich had also forgotten her watch so she asked a gentleman passing by for the correct time. The man's watch was ten minutes slow, but he thought it was 15 fast. Taking into account the errors in the watches, who was at the bank first and at what time did they arrive?
AnswerMr. Greenwich arrived first at quarter to two. He was told a time that was actually 15 minutes faster than the true time. Mrs. Greenwich arrived at 25 after since she was told a time that was 25 minutes slower than the true time.
