Navigation Tables

Tables designed for solving common Time-Speed-Distance navigation problems are used by many teams to stay on-time. You can

design your own tables, using a spreadsheet or computer program,
purchase a book of tables listed in the Bibliography, or
go to the pages listed below and print the ones you want on your own printer.

Hints when printing tables:

Experiment with the font settings in your browser before printing. Many browsers use the font you use to view pages to control the size of the font used to print pages.
Several versions of each table are provided: plain text vs Netscape table-based, and versions with different spacing. Try printing a sample of each of the versions of a simple table before commiting to printing all the tables.
The Netscape versions of the tables adjust their size as you change the width of your browser window. Just resize you browser till you get a format you like.
If you really want to reformat the table and are handy with HTML, you can download the HTML source, edit it on your machine, and view the modified page locally.

Conversion: Seconds => Cents

This table converts from seconds into cents (hundredths of a minute).

Formula:         ___
    seconds x 1.6666 => cents

Conversion: Cents => Seconds

This table converts from cents (hundredths of a minute) into seconds.

Formula:
    cents x 0.60 => seconds

Speed => Rate

Some TSD navigation strategies are based on knowing the Rate ("minutes-per-mile") at your assigned speed. This table shows the minutes to travel one mile at various speeds. The table can be used to convert MPH to minutes-per-mile and KPH to minutes-per-kilometer.

Formula:
       60
     -------  =>  Rate
      Speed

Perfect Time to Travel

With a few additions, you can get time perfect time to cover any distance at any assigned speed:

Look up the time to cover the whole miles in the table
Look up the time to cover the tenths, moving the decimal place one position to the left
Look up the time to cover the hundredths, moving the decimal place two positions to the left
Add the three numbers together to get the perfect time

For example, the perfect time to cover 2.73 miles at 39 MPH:

                                               2 . 7  3
                                               v   v  v
                                               |   |  |
   3.077   Time to cover 2 miles   <-----------   /  /
              at 39 MPH                          /  /
 + 1.077   Time to cover 7 miles is 10.77, <-----  /
              then move decimal 1 place           /
 + 0.046   Time to cover 3 miles is 4.61, <-------
              then move decimal 2 places
  ------
   4.200 = Time to cover 2.73 miles at 39 MPH.

This table can be also be used for kilometers and kph.

Formula:
     DISTANCE-in-miles x 60
     ----------------------  =>  TIME-in-minutes
          SPEED-in-mph

Note: You may want to switch your printer to Landscape mode to print these tables.
