Shivani walks from point A to B at 3 km/h and returns by bicycle at 12 km/h. Her return journey takes 2.5 hours less than her outward journey. Find her time for the entire journey.
\n" ); document.write( "

Let time spent walking, be T
\n" );
document.write( "Then time spent riding = T - 2.5
\n" );
document.write( "We then get the following DISTANCE equation: 3T = 12(T - 2.5)
\n" );
document.write( "3T = 12T - 30
\n" );
document.write( "3T - 12T = - 30
\n" );
document.write( "9T = 30
\n" );
document.write( "Time spent walking, or 
\n" );
document.write( "Time spent cycling: 
\n" );
document.write( "Time taken to cover entire journey:  \n" );
document.write( "

\n" );
