    Answer:After 3 hours, 9cm of snow will be left.

    Step-by-step explanation:

    Let h = height of snow=10cm

    Snow melt at the rate of 1/3 cm per hour

    After 3 hours, snow melted will be 1/3cmhr^-1 * 3hours=1 cm

    Depth of snow after 3hours = (10-1) cm = 9cm

    After 3 hours, the depth of snow on Cherry street will be 9 cm

    Step-by-step explanation:

    1. First let us list or the parameters given

    Original depth = 10 cm

    melting rate = 1/3 cm per hour, which means after every 1 hour, a depth of 1/3 cm melts.

    2. Next, let us find the depth that has melted after 3 hours:

    1 hour = 1/3 cm

    ∴ 3 hours = 1/3 * 3 = 1 cm.

    So, after 3 hours at a melting rate of 1/3 cm, a total depth of 1 cm had melted

    3. To find the depth of snow on the road after 3 hours, we will subtract the amount melted after 3 hours from the original depth of snow on the road:

    Original depth - depth melted after 3 hours = 10 - 1 = 9 cm.

    Therefore after 3 hours the depth of snow left on the road is 9 cm.
