Answer:C
At 3:40, the hour and minute hands of a clock make the following angle:
A. .120° B. .125° C. 130° D. 135°
Explanation: In 12 hours, the hour hand tracked the angle. = 360 degrees.It sketched an angle of (360/12 x 11/3 )° = 110° in 11/3 hours.In 60 minutes, the angle drawn by the minute hand equals 360°.It sketched a 40-minute angle of =(360/60 x 40)° = 240°.The required angle is (240 - 110)°, which equals 130°.
