Answer 1

$\huge \mathcal \red {Answer}$

In physics, a force is any interaction that, when unopposed, will change the motion of an object. A force can cause an object with mass to change its velocity, i.e., to accelerate. Force can also be described intuitively as a push or a pull. A force has both magnitude and direction, making it a vector quantity

What percentage of 1 hour is 1 minute and 12 seconds?

How do I know if I have psoriatic arthritis (PsA)?

“What Percentage of 1 hour is 1 minute and 12 seconds?”

Let’s turn that question into operations, symbols, and functions:

(The Bold Letters in the equations represent what I have changed.)

“What % * 1 hour = 1 minute + 12 seconds.”

For those who are confused, the term “of” means to multiply. Such as “10% of 200 is 20” etc.

Let me help myself by turning all numerals into seconds because I am still an amateur in doing math with time and clocks:

(All numbers are in seconds)

What % * 3600 = 60 + 12.

Let me simplify one of the sides:

What % * 3600 = 72

The equation says that a percentage of 3600 is equal to 72.

Well, let “a” represent the number that we are looking for.

a * 3600 = 72

We can simply find “a” by doing the inverse operation.

Following the rules of

a * b = c

c / b = a

c / a = b

etc.

So…

72 / 3600 = a

Simplifying one of the sides will give us:

0.02 = a.

We found a! We can turn that “a” into a percentage by multiplying it by 100.

0.02 * 100 = 2 = 2%.

Therefore we can finally say that

2% of 3600 is 72.

OR, in this case…

2% of 1 hour is 1 minute and 12 seconds.
