At a certain time, Jacob notices that his digital watch reads a minutes after two o’clock. Fifteen minutes later, it reads b minutes after three o’clock. He noticed that a is six times greater than b. What time was it when he looked at his watch for the second time?

From 2:a to 3:b is 15 minutes, so (60 + b) − a = 15, giving a − b = 45. Given a = 6b, we get 5b = 45, so b = 9. The second time was 3:09.

    1. The time elapsed from a minutes past two to b minutes past three is 15 minutes. Expressing both in minutes after two o’clock gives the relation (60 + b) − a = 15, which simplifies to a − b = 45. Given that a = 6b, substituting gives 6b − b = 45, leading to 5b = 45 or b = 9. Therefore, Jacob’s watch read 3:09 at the second viewing.
