Question

When minute hand of a clock rotates through 180 degree then hour hand rotates thrugh?

Answer 1

minute hand takes 360° to complete an hour while in that time hour hand only moved one set. (30°). so if minute hand moves 180° as they're in direct proportion, hour hand moves 15°.

Answer 2

Answer:

An hour hand rotates through 15 degree

Step-by-step explanation:

The angle between two consecutive numbers in a clock is 30 degree

When a minute hand completes 60 minutes, it rotates through 360 degrees and an hour hand rotates through 30 degree

Therefore when a minute hand completes 30 minutes, it rotates through 180 degrees and an hour hand rotates through 15 degree

Therefore the hour hand rotates through 15 degree
