Question

estimate the size of a crowd standing along a 1 mile section of a parade route that is 10 feet deep on both sides of the street. assume that each person occupies 2.5 square feet. a 21,120 people b 42,240 people c 84,480 people d 168,960 people

Explanation:

Step1: Convert miles to feet

1 mile = 5280 feet.

Step2: Calculate the total area

The parade route is 1 mile (5280 feet) long and 10 feet deep on both sides, so the total depth is \(10\times2 = 20\) feet. The area is length × depth, so \(5280\times20 = 105600\) square feet.

Step3: Calculate the number of people

Each person occupies 2.5 square feet, so the number of people is \(\frac{105600}{2.5}=42240\).

Answer:

B. 42,240 people
