I know that to be collinear, two or more points must be in the same line. But do the points have to be coplanar in order to be collinear?

Two cars travel in the same direction along a straight highway, one at a constant speed of 55 mi/h and the other at 60 mi/h.

1. Assuming that they start at the same point, how much sooner does the faster car arrive at a destination 13 mi away?

2. How far must the faster car travel before it has a 15-min lead on the slower car?

Thanks and please show me how you did it!

2=1? Is it Possible???

Assume that a = b.

Because a = b, one can also assume that a^2 = ab.

Now we can see that following is possible: a^2 – b^2 = ab – b^2.

Now factor both sides: (a – b)(a + b) = b(a – b).

Now we can divide both sides by (a – b):

[(a – b)(a + b)]/(a - b) = [b(a – b)]/(a - b)

This cancels out the (a – b)’s in the problem, we are now left with:

a + b = b.

Earlier we defined a = b so now we can substitute a for b:

b + b = b which can also be written: 2b = b.

Now we divide both sides by b:

2b/b = b/b

Now all the b’s cancel leaving 2(1) = 1 which an also be written:

2 = 1

AMAZING!!!!!!!!!!!!
