求英文高手!解题目意思!
(a) After running for 10 minutes, find the size of the angle in degrees made by
(i ) the minute- hand
(2) the hour hand
(b)Referring to the figure, find the marked angle between the minute-hand and the hour-hand at 10:10.
求解释,及做题方法.(图是自己画的,可能不太好.)
It's easy. The angle is composed of 2 angles, one is from 12 to 3 , that is 360*2/12=60 degrees, the other is from the hour hand direction to 12, that is 60-30*2/12=55 degrees. So, the angle is 60+55=115 degrees.
