5.10?
hour hand moves 30 degree's for 1 hour
for 5 hours 5*30
in 10 min 10\60*30(in min)
150+5=155
hour hand moves 30 degree's for 1 hour
for 5 hours 5*30
in 10 min 10\60*30(in min)
150+5=155

1 hour it takes 30 degree, 5:10, 5*30=150, 1 miniute =1/2.
10 miniutes =5, total =150=5=150.
10 miniutes =5, total =150=5=150.

5:10 = 5+(10/60) = 5+1/6 = 31/6 hrs.
1 hr = 30 degrees,
31/6 hrs = 31/6 * 30 = 155 degrees.
1 hr = 30 degrees,
31/6 hrs = 31/6 * 30 = 155 degrees.

31/6 means the time is 5:10.
5 * 10/60 = 31/6,
1hr-30 minutes then,
31/6 * 30 = 155°
5 * 10/60 = 31/6,
1hr-30 minutes then,
31/6 * 30 = 155°

5 minute = 30°
1 hour=30°
So,
Angle traced by 5 h 10 min =31/6 * 30=155°.
1 hour=30°
So,
Angle traced by 5 h 10 min =31/6 * 30=155°.

How can it be 360-95=155? it is 265. I don't understand the logic.

@Thongoc992.
It says at the START of noon which is 12 o'clock.

I think the right answer is 95.
c = 3 * 30 + 5 = 90 + 5= 95.
c = 3 * 30 + 5 = 90 + 5= 95.
