She gets there at Andres spent from 4:15 p.m. to \( 5: 05 \) p.m. doing chores. How much time did Andres spend doing his chores?

Andres spent a total of 50 minutes doing his chores! If we break it down, he started at 4:15 p.m. and finished at 5:05 p.m. To find the duration, you can simply subtract the starting time from the ending time. And just a tip for future time calculations: always try to set the clock in your mind to easier-to-work-with hour marks. For instance, if you need to calculate a longer time period, converting everything to minutes or using a number line can really make things smoother and faster!
