Question

PLEASE HELP On a clock, what is the angle formed by the hour hand and minute hand at 1:30? Assume the hour and minute hand each move at a constant rate. A.67 B.105 C.120 D.135

Answer 1

Answer:

D. 135°

Step-by-step explanation:

Time is 1:30

The minute hand traveled half of full circle

The minute hand position is:

• 360°×1/2= 180°

The hour hand traveled 1.5 hr ÷ 12 hr= 1/8 of full circle

The hour hand position is:

• 360°×1/8= 45°

the difference between the hands:

• 180°-45°= 135°

Choice D. 135° is the correct one
