Question

When the second hand has moved from 5 to 8, how many degrees has it turned through​

Answer 1

Answer:

5to6=360

6to7=360

7to8 =360

total =360+360+360

=1080degrees

Answer 2

It has turned through 90°.

Explanation:

As we know that , the total number of marks written on a clock = 12  ( from 1 to 12)

The distance traveled by second hand from 5 to 8  = 8-5 =3

Fraction of distance traveled by second hand from 5 to 8  = $\dfrac{3}{12}=\dfrac{1}{4}$

Also, we know that a complete angle is of 360°.

Now ,  Number of degrees has it turned through​ = (Fraction of distance traveled by second hand from 5 to 8 ) x (complete angle )

$=\dfrac{1}{4}\times360^{\circ}\\\\=90^{\circ}$

Hence, it has turned through 90°.
