Question

Physics experts.. Please answer.. BRAINLIEST answer will be marked if you answer correctly.

An insect moves along the sides of a wall of dimensions 12m x 5m starting from one corner and reaches the diagonally opposite corner. If the insect takes 2s for its motion, find the ratio of average speed to average velocity. ​

Answer 1

$\huge{\boxed{\red{\it{Answer}}}}$

Average speed = Total distance/Total time taken

= Hypotenuse/2s

$h {}^{2} = 12 {}^{2} + 5 {}^{2} \\ \: \: \: \: \: \: = 144 + 25 \\ \: \: \: \: \: \: = 169 \\ \: \: \: \: \: \: = 13 {}^{2} \\ \: \: \: h = 13$

So, Average speed = distance/time

= 17/2 m/s.

Average velocity = displacement/time

= 13/2 m/s.

So, ratio will be => 17:13.

$\huge{\boxed{\sf{Answer=17:13}}}$
