Mia walked n feet per minute and arrived at the clinic 10 minutes late. How fast should she have walked to have arrived on time?
\n" ); document.write( "--------
\n" ); document.write( "d = distance
\n" ); document.write( "d = n*t
\n" ); document.write( "t = d/n --> 10 minutes late
\n" ); document.write( "---
\n" ); document.write( "t-10 = d/(n+s) [s = increase in speed]
\n" ); document.write( "Solve for s
\n" ); document.write( "(t-10)*(n+s) = d
\n" ); document.write( "n(t-10) + s(t-10) = d
\n" ); document.write( "s = (d - nt + 10t)/(t-10)
\n" ); document.write( "s = 10t/(t-10)
\n" ); document.write( "=========
\n" ); document.write( "Walking $\"n+%2B+10t%2F%28t-10%29\"$ --> on time
\n" ); document.write( "= $\"%28d+-+10n+%2B+10t%29%2F%28t-10%29\"$ \r
