Henry can ride his horse at 4mph and get to the battlefield on time. If he stops for 1 hour to make a speech to his troops, he must ride 5mph for the whole trip to get to the battlefield on time. How far is it to the battlefield?
\n" ); document.write( "-----------
\n" ); document.write( "Let distance to the battlefield be \"x\":
\n" ); document.write( "No-delay DATA:
\n" ); document.write( "rate = 4 mph ; time = d/r = x/4 hrs
\n" ); document.write( "-----
\n" ); document.write( "With-delay DATA:
\n" ); document.write( "rate = 5 mph ; time = d/r = x/5 hrs
\n" ); document.write( "-----
\n" ); document.write( "Equation:
\n" ); document.write( "no-delay time = delay-time + 1
\n" ); document.write( "---------------
\n" ); document.write( "x/4 = (x/5)+1
\n" ); document.write( "-----
\n" ); document.write( "5x = 4x + 20
\n" ); document.write( "x = 20 miles (distance to the battlefield)
