Once you have a really good idea of what the problem is about, you
need to think about what to do next. Have you seen this type of question
before? Being able to classify a problem can make it much easier to lay
out a plan to solve it. You should almost always make a quick drawing of
the situation. Label important events with circled letters. Indicate any
known values, perhaps in a table or directly on your Sketch.

Because you have already categorized the problem, it should not be too
difficult to select relevant equations that apply to this type of situation.
Use algebra (and calculus, if necessary) to solve for the unknown
variable in terms of what is given. Substitute in the appropriate numbers,
calculate the result, and round it to the proper number of significant
figures.
