    1.4/1 = 7.7/x
    1.4x = 7.7
    x = 7.7/1.4
    x = 5.5

    Sam is 4 feet tall and his shadow is 2.5 feet long. If the flagpole has a 30-foot shadow, how tall is the flagpole?

    X over 4 = 30 over 2.5
    2.5x= 4•30
    ----- = 120 divided by 2.5
    X = 48 feet

    The flagpole is 48 feet tall.
