Answer: B. x^8y^8
Have a great day.
Since the problem is requesting the answer in minutes, we are going to convert the speed of Mr. Peter to miles per minutes; to do that, we are going to multiply his speed by the multiplier

:

Now, to find the distance from Boston to Worcester, we are going to use the distance formula:

where

is the distance

is the speed

is the time
We know that the speed of Mr. Peter is

and his time is 30 minutes. Lets replace those values in our formula:


Now, lets concentrate on Mr. Peter clone, Mr. P:
Lets convert the speed of Mr. P to miles per minute:

We also know that they will cover the same distance, 30 miles. Lets replace the values in our formula one more time to find t:




But since Mr. P <span>leaves 5 minutes after Mr. Peters, we need to add those 5 minutes to M. P's time:
</span>

We can conclude that Mr. P will arrive first, 5 minutes before Mr. Peter.
Answer:
A nice way to show it is through the unit circle.
In the unit circle, the point at angle theta from the origin has a y value of sin theta.
If you rotate a point 360-theta degrees from the origin, that is like rotating it theta degrees "backwards", or downwards, which is going to yield the same exact point, reflected through the x-axis. In other words, the y value, or sin(360-theta), is exactly -sin(theta).
