Re TY
\n" ); document.write( "153mi is the distance traveled in 1hr w/o stopping at the station.
\n" ); document.write( "w/o stopping at the station... $\"153mi%2F%281hr%29+=+153mph\"$
\n" ); document.write( "avg mph = total distance /total time
\n" ); document.write( "x time spent at the station(s)
\n" ); document.write( " $\"153mi%2F%281hr+%2B+highlight_green%28x%29+%29+=+72kmph\"$ | Cross Multiplying to solve
\n" ); document.write( "72 + 72x = 153
\n" ); document.write( "72x = 81
\n" ); document.write( "x = 81/72 = 9/8 = 1.125hr = 1 1/8 hr,time spent at the stations per hour traveling.
\n" ); document.write( "checking: traveling for 2 hrs for ex
\n" ); document.write( " $\"306%2F2%281+%2B+1.125%29%29\"$ = 72kmph
\n" ); document.write( " \n" ); document.write( "
