    In 9 days will the second warehouse have 1.5 times more coal than the first one

    Step-by-step explanation:

    The coal left in warehouses after x days can be found using the equation:

    first warehouse: 185 - 15x second warehouse = 237-18x

    Let the second warehouse have 1.5 times more coal than the first one after n days then

    1.5 * (185 - 15n) = 237-18n which gives: 277,5-22,5n=237-18n and 40,5=4,5n 9=n
