Formula: $|30H - 5.5M| = |30(3) - 5.5(40)| = |90 - 220| = 130^\circ$. Instant solution in under 5 seconds.
Each minute mark on a clock represents $360^\circ / 60 = 6^\circ$. The minute hand at 40 minutes is at $40 \times 6^\circ = 240^\circ$. The hour hand moves $360^\circ / 12 = 30^\circ$ per hour, plus $0.5^\circ$ per minute. At 3:40, the hour...
