Two trains leave the station at the same time, one heading west and the other east. the westbound train travels at 90 miles per hour. the eastbound train travels at 80 miles per hour. how long will it take for the two trains to be 272 miles apart? do not do any rounding.

step-by-step explanation:

in the absence of parentheses, i will have to make some assumptions:   i interpret your (3x+5/y^6)(4y^3/5)​ to mean:

3x + 5     4y^(3/5)       (3x + 5)(4)

* =

    y^6             1               y^(6-3/5)

if this is not what you expected, repost your question using parentheses to indicate whether you meant

4y^3

    or   4y^(3/5)

    5

okay wait before i answer, is this for your points on a graph?
