AMO · 2027 · Grades 2-3 · Self-study SET 23 Question 14

How many times altogether do the hour hand and minute hand cross an even-numbered mark on a clock from 1 a.m. to 1 p.m.? Count each hand separately, even if both cross at the same instant. Count crossings after the starting time and up to and including the ending time. The source clock is an illustration of the face, not a picture of the stated starting time.
