    Number of miles traveled by Mary to work = 7 miles

    Step-by-step explanation:

    total distance traveled on the Map by Mary = 1 + 2.5 = 3.5 cm

    Scale of the map = 2 cm = 4 miles

    Hence 3.5 cm = (3.5 x 4) : 2 = 7 miles

    Step-by-step explanation:

    Given:

    Scale:

    2 cm to 4 miles

    Mary's drive to work:

    1 cm north

    = 1 cm * 4 miles/2 cm

    = 2 miles north

    2.5 cm west

    = 2.5 cm * 4 miles/2 cm

    = 5 miles west

    Total distance = (1 cm N + 2.5 cm W) * 4/2
