do you not have destroyer? only ask b/c answer IS in the book...

anway...its a distance between two points problem. both cars start at the same point (34th street)

point A = (7, -3)
point B = (3, 5)

distance = sqrt [(x2-x1)^2 + (y2-y1)^2]
= sqrt [(3-7)^2 + (5-(-3)^2)]
= sqrt [16+64]
= sqrt [80]
= 8.9

I really hope thats not the question you were asking.
Thats a gimme question.

yes, this is it. i didn't know how to start it because i never thought about the distance formula for this question. the speed wasn't given so i had no idea how to do it.

99% of problems that sound like this are dealing with distance. also, in order to be a rate problem you must be given a time frame in which "an event" takes place. check the pic ....

I don't think thats a dumb question. I can imagine myself overcomplicating things just like the OP. Can't remember the last time I saw that equation...

now that I see the rest of the question I see your problem, they added to much fluff to the question. Sorry for being rude. Forgiven? 😀

Use the answer key in the back of the section in the destroyer it does explain what to do for each question.
