AMC 12 late, AIME early
Number theory Difficulty 4.8 Find the answer

It is now 1:00 a.m. What time will it be 2023 minutes from now?

A number or a short expression. Spacing and $ signs are ignored.

Official solution

Note that 2023=33×60+432023=33 \times 60+43, and since there are 60 minutes in an hour, this means that 2023 minutes is equal to 33 hours and 43 minutes.

For 33 hours and 43 minutes to pass, 24 hours will pass and then 9 hours and 43 minutes will pass.

In 24 hours it will be 1:00 a.m. again.

In 9 hours and 43 minutes after 1:00 a.m., it will be 10:43 a.m.

ANSWER: 10:43 a.m.
