Question

An event lasts 1,560,000 milliseconds. Approximately how long did the event last in hours

Answer 1

First note that using dimensional analysis:
\[(\frac{ms}{1})(\frac{1000s}{ms})(\frac{1m}{60s})(\frac{1hr}{60m})\]
Will Convert a unit from ms to hours. Notice how all units cancell each other out except the hours.

Answer 2

Hold on, typo

Answer 3

\[(\frac{ms}{1})(\frac{1s}{1000ms})(\frac{1m}{60s})(\frac{1hr}{60m})\]

Answer 4

Thank you!(:
