6. DIMENSIONAL ANALYSIS Time Conversion Factors: RULES:

7.  4 min = ? Sec  360 sec = ? min  540 sec = ? min  960 sec = ? min  14 min = ? sec  17.6 min = ? sec DIMENSIONAL ANALYSIS

8. Multi-Step Conversions: When a direct relationship “Conversion Factor” is not known an “in common” unit has to be used 4 hr = ? sec 15000 sec = ? Hr 3.5 hr = ? Sec 800 sec = ? hr DIMENSIONAL ANALYSIS
