Math Marcus started painting at \( 2: 37 \). He painted for 42 minutes. When did Marcus finish painting? Enter your answer on the clock.

Marcus began painting at 2:37. If we add 42 minutes to that, we need to break it down into hours and minutes. Starting from 2:37, adding 23 minutes takes us to 3:00, and then we have 19 minutes left to add. So adding those 19 minutes brings us to 3:19. Therefore, Marcus finished painting at 3:19. Visualizing time on a clock can be a great way to understand how minutes and hours work together. Think of the clock face as a circular reference where each hour is split into 60 mini-sections; this can enhance your time management skills! Not keeping track of how many minutes you've added can lead to mistakes. When adding time, ensure you keep counting up from each reference point—like moving from one hour to the next—so you don’t get lost in the numbers!
