Question

By how many degrees does the minute hand move in the same time in which the hour hand move by 280

Answer 1

An hour hand moves 1/12 of the clock (if that makes sense) in an hour. A clock is a circle with 360 degrees, so it moves 30 degrees per hour. This means that every minute it moves 30/60 degrees, or half a degree.

Answer 2

Answer:

Degrees the minute hand move, when hour hand move 28° = 336°

Step-by-step explanation:

Hour hand

12 hour = 360°

1 hour =  $\frac{360}{12}$

= 30°

60minutes = 30°

1minute =  $\frac{30}{60}$° = $\frac{1}{2}$°

In hour hand, 1minute = $\frac{1}{2}$°

Minute hand

60minutes = 360°

1minute = $\frac{ 360}{60}$ =6°

In minute hand, 1minute = 6°

Given, degree which hour hand moves = 28°

To move  28° hour hand takes 56minutes (∵ 1minute = $\frac{1}{2}$°)

Hence in 56minutes, the  minute hand move = 56×60 = 336°(∵ 1minute = 6°)

∴Degrees the minute hand move, when hour hand move 28° = 336°
