Since 60 miles per hour is the same as 1 mile per minute, and Austin is 65 miles away, it will take Dan 65 minutes to get there.

Therefore, he will arrive at 4:05 p.m.

Where are P and Q?

Please post a diagram.

Please share the grid that you are talking about so we can answer your question.

So what we're looking at here is a right triangle with sides as follows: 

Opposite side from theta: 6

Adjacent side to theta:      8

Hypotenuse                      10

I used the pythagorean theorem to find the opposite side.

Therefore, since csc = hypotenuse / opposite, the answer is 10/6 = 5/3

My eyes might be playing tricks on me, but I see no diagram, so I don't know where I is...

What grid?

Please proofread your questions.

How many skaters are there? I think you forgot to include the number. Please proofread your questions as opposed to copy and pasting them from a site with latex or other images on it.
