Question

Clock wise angle from minutes hand to hour hand at 7 o'clock is what (a)240° (b)230° (c)220° (d)210° (e)200°

Answer 1

d

Explanation:

At 7 o' clock the minute hand is at 12 and the hour hand at 7

There is 360° in a complete revolution, thus between 7 and 12

angle =
`(7)/(12)` × 360° = 7 × 30° = 210° → d

Answer 2

Option D) Angle at 7 o'clock = 210 degrees

Explanation:

The whole clock = 360 degrees

Every 1 hour = 360/12

Every 1 hour = 30 degrees

Angle at 7 o'clock = 30*7

Angle at 7 o'clock = 210 degrees
