Question

An insect moves along the sides of a wall
of dimension 12 m x 5 m, starting from
one corner and reaches the diagonally
opposite corner. If the insect takes 2 seconds for
its motion, then find the ratio of average
speed to average velocity of insect.
a.17:13
b.12:5
c.13:5
d. 17:12​

Answer 1

Answer:A 17:13

Explanation:

Displacement or shortest distance is 13 as by finding resultant of 12 and 5

Distance travelled is 5+12=17

17/2 :13/2

=17:13

Answer 2

Answer:

$12m \times 5m = 60m. \\ \\ \\ 2second \: \\ \\ 60 \div 2 = 30 \\ \\ \\ 30 \div 1.5 \\ \\ the \: ratio \: is \: or \: = option \: d17..13$

Explanation:

option d) is correct. 17:13.priest thanks my answer..
