So I was doing my homework quite merrily until I go to the end where I ran into word problems.. (why do they always stick them at the end)

Can you guys point me into the right direction?

Q#1.

The minute hand on a clock is6 cmlongand the hour hand is4 cmlong.Give an expression for,dthe distance between the tips of the hands, in terms ofa, the angle between the hands.

What Does "d"=?

I drew a lame picture of the clock hands neatly labeled. I noticed you can form a triangle and thus use Pythagorean to find the distance between the 2 points. But Im not sure which side is the longer side? Do you guys think it should be $\displaystyle 6^2+4^2=c^2?$My Plan of Attack:

2nd, I think, once I know the 3 side lengths, I can use either Cosine law or Sine law to find the angle..

And what is the question asking when they are asking for an expression for "d"?

Q#2.

At noon, ship A passes 8 km west of a harbour, heading due south at 10 km/h. At 9 a.m., ship B had left the harbour, sailing due south at 5 km/h. Give an expression ford, the distance between the two ships, in terms oft, the number of hours after noon.

Confused.My Plan of Attack:

I have no idea why I can't handle word problems.

TIA as always
