Please give the answer

Answer 1

Answer:

Your answer is 2.09secs hope it helps you.

Explanation:

Speed of the insect = 10cm/sec

Then find the face diagonal of the room by the formula=√l^2+b^2+h^2.You will get the answer as 2√110cm=distance the insect had to travel.

By applying speed =Distance /time

&Time=Distance /speed=2√110/10=2.09secs.
