Do you remember the pythagorean theorem?

[akaerin]

yes, (h^2=a^2+b^2) but how am I supposed to find the distance with two unknowns?

[booksoverbombs]

Is the distance from P to C a fixed value, or does it change depending on the value of x?

[korean_guy_01]

Remember to have the correct units. kilometers and meters do not automatically match up. I would convert to kilometers.

A) Pythagorean Theorem
B) Use a certain given factor in the problem and the answer in A to get the expression.
C) Distance from A to P = expression 1. Distance from P to C = Answer A = expression 2. expression 1 + expression 2 = ?
D) Use expression 1 in C and a certain given factor to get t1. Use expression 2 in C and a certain given factor to get t2. t1+t2 = ?
E) What are we minimizing? How can we use the available information to get everything in the correct units? Minimizing/Maximizing/Optimization deals with what Calculus concept?
F) Solve for expression D
G) Using the 1.5km given to you, what is xp (the x value, according to Peter)? Can you make a similar expression like that in C with this information? Evaluate this like you did in Part D and compare this to what you got in Part D.

[korean_guy_01]

For part D, notice that expression 2 = Answer B. Forgot to point that out, but you should notice that anyway.

If you cannot get your nicely scanned problem, go and shoot yourself.

Wow, that wasn't completely unnecessary or anything.

[akaerin]

It wasn't actually scanned, the question was on CD.

But, you know, thanks for your help.
