Question

The minute hand of an 84 long The distane covered by the trip of minute hand from 10:10am to 10:25 is​

Answer 1

Answer:

It has travelled 55.44 meters.

It is a large distance as the length of the minute's hand is almost

a meter long.

Step-by-step explanation:

The total time between 10:10 am and 10:25 am is 15 minutes.

We know that 5 minutes provides an angle of 30*.

So, 15 minutes, an angle of 90* is created.   (30 x 3)

Distance covered would be the length of the arc - $\frac{theta}{360} (2\pi r)$

Simplified much further, we get $(\frac{1}{4})(\frac{22}{7})84^2$

7 times 12 gives 84. So 7 simplifies 84 to 12.

Then, $(\frac{1}{4})(22) (12)(84)$

Then, we can write it as 22 x 3 x 84

Which is 66 x 84

Which is 5544 cm.
