    since they have the same rate/ you can conclude that they will meet at a point wherebthey have equal distances. That makes their distance both 80m. Since they can move 1 mile per second, 80 miles would be 80 seconds. :)

    u can use relative motion.they are coming toward each other so u can sum their rates.1+1=2m/s now u can find the time bye the equation X=VT which tends to 160=2t.solving for t u have T=8O. u can find the distance bye multiplying 80*1=80m

    around 42 parsecs. Give or take 2 drizzles, but make sure to convert from swizzles first.
