Answer:
The answer to your question is below
Step-by-step explanation:
Data
Methane: 1 carbon and 4 hydrogens
A sample 92 hydrogen atoms / carbons = ?
total atoms = ?
Process
1 : 4 :: x : 92
x = number of carbons
x = (92 x 1) / 4
x = 92 / 4
x = 23 carbons
Total atoms = hydrogen atoms + carbon atoms
= 92 + 23
= 115 atoms
Answer: 20 minutes.
Explanation:
Think of the water stream as being still (perhaps like a solid pavement), from the point of view of objects floating on the surface. (of course, from the POV of anyone standing on the banks, the water flows downstream). Think of the boat as a bike riding on the pavement. The boat just turned upstream and the hat fell into the water. In this POV, the hat lies on the surface and the boat/bike is riding away. For 20 minutes. Then (Katya realizes she lost the hat and turns back), the boat/bike needs exactly the same time, i.e., 20 minutes to come back to the hat, which rests at the same spot on the surface!
What makes the question initially confusing is the fact that the river flows with respect to the banks and one's mind is tempted to view the situation from there, which makes it much more complicated.
In physics this is referred to as choosing the suitable "frame of reference."
Given are three married couples.
So, let us assume there are 3 men and 3 women
They are sitting in a row of 6 empty seats
There is a definite order constraint that each woman will sit left to her husband. The first woman gets 3 options to choose from 3 available seats. The second woman has two options left as already one seat is filled by the first woman. The last woman has one option left. So, it is 
So, number of ways is 3! = = 6 ways.
