average travel time to work in major u.s. cities

Explanation:

Step1: Analyze the bar graph

The graph is about "Average Travel Time to Work" for major U.S. cities. We need to find the frequency (number of cities) for the time interval 25 - 30 minutes (assuming the x - axis labels are like 15 - 20, 25 - 30, 35 - 40 etc. and we look at the bar for 25 - 30). From the bar graph, we estimate the height of the bar for 25 - 30 minutes. Looking at the y - axis (frequency), if we assume the y - axis has markings and the bar for 25 - 30 minutes reaches up to around 20 (by visually inspecting the bar's height relative to the y - axis scale).

Step2: Match with options

The options are a.15, b.20, c.11, d.16. From our analysis of the bar graph, the bar for 25 - 30 minutes has a frequency around 20.

Answer:

B. 20
