Question

calculate the distance between minute hand and hour hand of a wall clock having time 12:15 p.m. as you hand clock be at 12 if the radius is 10 cm.​

Answer 1

Answer:The clock will move in a circular motion

The radius if the circle is 12 cm

So circumference= 2πr

= 2×22/7×12

=75.4 cm approx.

Degree covered in 25 minutes=

360/60×25

= 150°

Now, since distance covered in 1° =

75.4/360

= 0.209

Distance covered in 150° =

75.4/360×150 = 31.41 cm ( approx.)

So, the tip of the minute hand will cover a distance of 31.41 cm
