Finding when boat Q is northeast of boat P

[lioric]

Put $t=1$ in your vector. Does it point NE? How about $t = 2$ or $t=3$ etc. The question is, is there any value of $t$ that gives a vector that points NE.

I get it now
I have to find out by changing t which changes the values inside the bracket
Hence giving magnitude to i & j

I completely understand
Thank you very much

(2+t)i + (10t-15)j

2+t=10t-15
t-10t=-2-15
-9t=-17
t=-17/-9
t=1.889

So that's 1hr 53min 20sec past noon
Thank you very much
And thank you for being so patient with me

You are welcome. I'm curious what math courses you have had or are taking now.

Non actually
I just find questions here and there and try to attempt them
