Answer

The correct answer is: $43200$

Explanation

A hour has 60 minutes and each minute has 60 seconds, so multiply 12 hours by those conversion factors.

Steps:

  1. Convert hours to minutes: $$12\text{ hr}\times60\text{ min/hr}=720\text{ min}$$
  2. Convert minutes to seconds: $$720\text{ min}\times60\text{ s/min}=43200\text{ s}$$
  3. Or do it in one step: $$12\text{ hr}\times60\text{ min/hr}\times60\text{ s/min}=43200\text{ s}$$

Therefore, 12 hours = $43200\text{ s}$.
