Question

Find the angle between the minute hand of a clock and the hour hand when the time is 7:40 AM.

Answer 1

30 degrees is the correct answer. 1 round = 360 degrees. 7 - 8 = 1/12 of the total circle. Therefore angle between 7 and 8 = 360/12 = 30 DEGREES. :) :)

Answer 2

the best formula to calculate angle
$|30h - \frac{11}{2}m | \\ h = 7 \\ m = 40 \\ |30 \times 7 - \frac{11}{2} \times 40 | \\ |210 - 220| \\ = | - 10 | \\ = 10$
