Two circles, one of radius 5 inches, the other of radius 2 inches, are tangent at point P. Two bugs start crawling at the same t

lawyer [7]

Answer:

40 minutes

Step-by-step explanation:

The circumference of the larger circle is ...

C = 2πr = 2π(5 in) = 10π in

The bug navigates the circumference at 3π in/min, so will take

time = distance/speed = (10π in)/(3π in/min) = 10/3 min

to travel once around.

The circumference of the smaller circle is ...

C = 2πr = 2π(2 in) = 4π in

The bug navigates this circumference at 2.5π in/min, so will take

(4π in)/(2.5π in/min) = 8/5 min

to travel once around.

The bugs will meet at a time that is the least common multiple of these times. Both can be expressed in 15ths of a minute as ...

{50/15, 24/15}

Then the LCM of these will be ...

(1/15)LCM(50, 24) = (1/15)(50×24)/GCD(50, 24) = 1200/30 = 40

It will be 40 minutes before the bugs next meet at point P.

___

A graphing calculator can make use of the mod function to show when the bugs meet at point P (total is displacement of the two bugs from P is zero). It shows the meeting occurs after 40 minutes.
