Convert measurements within a system and use unit reasoning to choose the correct scale.
Find every equivalent or sensible measurement choice
Problem
Identify \(\text{every}~\text{measurement}\) equal to \(1.5~\text{hours}\).
A. \(90~\text{minutes}\) B. \(1~\text{hour}~30~\text{minutes}\) C. \(150~\text{minutes}\) D. \(5,400~\text{seconds}\) E. \(0.15~\text{day}\) F. \(75~\text{minutes}\)
Big Picture
What this problem is really about
Use one common time unit as a benchmark for every representation. Convert the target duration first, then rewrite mixed hours and minutes, seconds, days, and plain minutes into that same unit before comparing. Similar-looking decimals or numbers are not evidence of equivalence; each unit relationship must be applied completely.
