wer = 40 * 12 = 480 BPS/week
\n" ); document.write( "---
\n" ); document.write( "wsr = we(1/5) = 480(1/5) = 96 BPS/week
\n" ); document.write( "---
\n" ); document.write( "rate = units / time
\n" ); document.write( "time = units / rate
\n" ); document.write( "---
\n" ); document.write( "answer:
\n" ); document.write( "t = (500 BPS) / (96 BPS/week) = 5.208 weeks
\n" ); document.write( "t = 5 weeks, 2 days
