# A clock challenge. An analog clock reads 7:30 AM now. ![[1 teaching/summer program 2023/puzzles-and-problems/---files/Pasted image 20230829101715.png]] Some questions for you! (1) What is the angle between the hands at 7:30AM? (2) At what time (**exactly, in fractions**) are the hands $90^{\circ}$ to each other, right after 7:30AM? (3) At what time (**exactly, in fractions**) do the hands overlap, right after 7:30AM? Come for stickers.
