Which activity has a duration that is 1.5 times Planning?

• A. Appendix
• B. Writing the Report
• C. Planning
• D. Executive Summary

Answer: (B)

The key idea here is comparing how long each activity lasts relative to Planning. If an activity’s duration is 1.5 times the Planning duration, it takes 50% longer than Planning.

Writing the Report fits that relation because its duration is one and a half times as long as Planning. For example, if Planning takes 2 days, Writing the Report would take about 3 days. This makes it longer by 50%, which matches the requirement.

Appendix and Executive Summary are typically shorter or not tied to that 1.5× relationship, and Planning itself is the base duration, not the longer one. So Writing the Report is the best match for having a duration 1.5 times Planning.
