questions 35 and 36 are based on the following information.

Explanation:

Question 29

Step1: Convert feet per minute to feet per hour

Julio walks 264 feet per minute. There are 60 minutes in an hour, so multiply by 60: \(264 \times 60 = 15840\) feet per hour.

Step2: Convert feet per hour to miles per hour

Since 1 mile = 5280 feet, divide by 5280: \(\frac{15840}{5280} = 3\) miles per hour.

We compare the bar heights (number of orders) for each year (2006, 2007, 2008, 2009) to the mean of 573. Visually, 2008's bar height is closest to 573.

Step1: Estimate orders in 2008 and 2009

From the graph, 2008: ~675, 2009: ~390 (approximate values from bar heights).

Step2: Calculate decrease amount

\(675 - 390 = 285\)

Step3: Calculate percent decrease

Percent decrease = \(\frac{285}{675} \approx 0.422\) or 42%, closest to 40%.

Answer:

A. 3 miles per hour
