The distance traveled to the top of the escalator to the bottom is 52 ft
Here, we want to calculate the distance a person on the escalator travel from the bottom to the top of the escalator
Firstly, we need a diagrammatic representation to understand this
We can form a right-angled triangle with the information given in the question.
The diagram is shown as below;
From the question, by simply calculating the hypotenuse of the right-angled triangle, we can get the distance traveled from the bottom of the escalator to the top
Let us call this distance d
We can now use the appropriate trigonometric ratio
The trigonometric ratio to use here is the sine since we have the opposite and we want to calculate the hypotenuse
Mathematically;
Factor this by grouping. Group the first two terms together and then the second 2 terms together. The idea here is that, after grouping, what you can pull out in both groups is the same. Like this:

Now work on finding a common thing between the 2 groups:

See, what you have in common there now is the (x-9) that you can factor out:

And that is factored completely.
Answer: 63
Step-by-step explanation:
14.5x1.5=21.75
15x2.75=41.25
21.75+41.25=63
Answer:
1) 375
2) 2 because 24% of 100 is 24 and 22% is 22 so 24-22=2
