Here are my equations so far: x + y = 490 and x + y = 11.4 hours. And x = 35 and y = 45. And maybe 490 = 35x + 45y. I also made 490 divided by 11.4 hours = 42.98 adverage "WHAT" ?
You seem to have defined your variables to mean at least three different things. It might help to specify one meaning, and then work from there.
a) Working from the step-by-step instructions provided earlier, what variable have you picked to stand for the time the first driver spent driving?
b) What was the rate of the first driver?
c) Using "d = rt", what expression do you get for the distance that the first driver covered?
Please reply with answers to the above, and then we'll start working on the next step in the instructions.
Thank you!
