Answer:
20 feet
Explanation:
To find the length of the totem pole's shadow, we need to know that the rate between the man's height and his shadow's length is the same rate of the totem pole's height and its shadow's length.
So, if we call the length of the totem pole's shadow 'x', we have:
6 feet / 2.5 feet = 48 feet / x feet
x = 2.5 * 48 / 6
x = 20
So the length of the totem pole's shadow is 20 feet.
