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) \n" ); document.write( "================ \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( "================= \n" ); document.write( " |
