Answer 1

n important formula to remember when doing questions like this is
rate×time=distance


For car A you have:
(rate of car A) x (2 hours) = distance

Can you set up a similar equation for car B?

Answer 2

Make a table. Like this:

Answer 3

the distance traveled by both is d (we just don't know what it is, and it really doesn't matter!)

Answer 4

ahhh..

Answer 5

We know the times for both: A is 2 and B is 1.5:

Answer 6

so the rate woud be..

Answer 7

As far as the rates go, we know that B traveled 15 miles per hour faster than A. Since we don''t know A's rate we will call it r. Then A would be "r", and B would be "r+15"

Answer 8

Now we are ready to set up our equation. Since both the cars traveled the same distance, and that distance for both is "d", and they are both equal to "d", they are both equal to each other. So here is the equation:
