Key Insights

• Walking is only used for commutes of 10 km or less—beyond that, its usage drops to zero.
• Bicycling is the dominant mode for 2–10 km, peaking at 50,000 commuters in the 2–5 km range.
• Car usage rises with distance, becoming the top choice for over 15 km (40,000 commuters).
• For distances ≤10 km, bicycling (124,000) is used by more people than walking (47,000), and car use (56,000) slightly exceeds public transit (49,000).

Step-by-Step Solution

Question 1: Walking vs. Bicycling for Round-trip Distances ≤ 10 km

Complete Statement:

For round-trip distances less than or equal to 10 km, the number of persons travelling to work by walking was ______ the number of persons travelling to work by bicycling.

Breaking Down the Statement

• Statement Breakdown 1:
  • Key Phrase: round-trip distances less than or equal to 10 km
  • Meaning: Only consider trips that are 10 km or less.
  • Relation to Chart: Include the first three distance categories: \(\mathrm{d \leq 2\text{ km}}\), \(\mathrm{2 < d \leq 5\text{ km}}\), and \(\mathrm{5 < d \leq 10\text{ km}}\).
  • Important Implications: Sum totals for these categories only, not the longer distances.
• Statement Breakdown 2:
  • Key Phrase: number of persons travelling to work by walking
  • Meaning: The total count of commuters who walk within these distance ranges.
  • Relation to Chart: Identify the data for walking in each relevant distance group.
  • Important Implications: Add the numbers for walking for each distance within the range.
• What is needed: Whether the total number of walking commuters is less than, equal to, or greater than the total number of bicycling commuters for distances ≤ 10 km.

Solution:

• Condensed Solution Implementation:
  Sum the number of people commuting by each mode (walking and bicycling) for the first three distance categories, then compare totals.
• Necessary Data points:
  Walking: 30 (≤2 km), 10 (2–5 km), 7 (5–10 km). Bicycling: 34 (≤2 km), 50 (2–5 km), 40 (5–10 km).
• Calculations Estimations:
  Total walking: \(\mathrm{30 + 10 + 7 = 47}\) thousand. Total bicycling: \(\mathrm{34 + 50 + 40 = 124}\) thousand.
• Comparison to Answer Choices:
  47 thousand (walking) is less than 124 thousand (bicycling), so the answer is 'less than'.

FINAL ANSWER Blank 1: less than

Question 2: Car vs. Public Transit for Round-trip Distances ≤ 10 km

Complete Statement:

For round-trip distances less than or equal to 10 km, the number of persons travelling to work by car was ______ the number of persons travelling to work by public transit.

Breaking Down the Statement

• Statement Breakdown 1:
  • Key Phrase: round-trip distances less than or equal to 10 km
  • Meaning: Only consider trips that are 10 km or less.
  • Relation to Chart: Include the first three distance categories: \(\mathrm{d \leq 2\text{ km}}\), \(\mathrm{2 < d \leq 5\text{ km}}\), \(\mathrm{5 < d \leq 10\text{ km}}\).
• Statement Breakdown 2:
  • Key Phrase: number of persons travelling to work by car
  • Meaning: The total count of commuters who use a car within these distance ranges.
  • Relation to Chart: Identify the car mode data for each applicable group.
• What is needed: Whether the total number of car commuters is less than, equal to, or greater than the total number of public transit commuters for distances ≤ 10 km.

Solution:

• Condensed Solution Implementation:
  Sum the number of people commuting by car and public transit for the first three distance categories, then compare totals.
• Necessary Data points:
  Car: 9 (≤2 km), 20 (2–5 km), 27 (5–10 km). Public transit: 2 (≤2 km), 17 (2–5 km), 30 (5–10 km).
• Calculations Estimations:
  Total car: \(\mathrm{9 + 20 + 27 = 56}\) thousand. Total public transit: \(\mathrm{2 + 17 + 30 = 49}\) thousand.
• Comparison to Answer Choices:
  56 thousand (car) is greater than 49 thousand (public transit), so the answer is 'greater than'.

FINAL ANSWER Blank 2: greater than

Summary

For round-trip distances of 10 km or less, there are fewer people walking (47,000) than bicycling (124,000) to work, and more people using cars (56,000) than public transit (49,000). Summing the relevant categories for each mode makes the comparisons clear.

Question Independence Analysis

Each question focuses on a different comparison—one on walking vs. bicycling, and the other on car vs. public transit—though they use the same distance range. The answers to the blanks don't depend on each other.
