Answer 2

Answer:  

The time required for a person standing 20 meter far to smell the perfume = 20 seconds

Step-by-step explanation:

Given that : A perfume bottle is opened then a person 10 meter far smells the perfume after 10 seconds of time

And we need to find the time required for a person standing 20 meter far to smell the perfume

Now, 10 meter far person smells the perfume in 10 seconds

So, 1 meter far person will smell in 1 second

⇒ The person standing 20 meter far will smells in 1 × 20 = 20 seconds

Therefore, The time required for a person standing 20 meter far to smell the perfume = 20 seconds
