traveling at 55miles/hour. She is 10 miles from home when her husband realizes
\n" ); document.write( " that she has forgotten her briefcase. How fast will he have to drive to catch her in two hours?
\n" ); document.write( ":
\n" ); document.write( "Find how far ahead White is at the start in terms of time (hrs):
\n" ); document.write( "time = 10/55
\n" ); document.write( "time = 5/11 hrs
\n" ); document.write( ":
\n" ); document.write( "White travel time = 2\"5%2F11\" or \"27%2F11\" hrs
\n" ); document.write( "Husband's travel time = 2 hrs
\n" ); document.write( ":
\n" ); document.write( "Let s = speed required for him to catch up in two hrs
\n" ); document.write( ";
\n" ); document.write( "When he catches up, they will have traveled the same distance
\n" ); document.write( "Write a dist equation from this fact: (Dist = time * speed)
\n" ); document.write( ":
\n" ); document.write( "2s = \"27%2F11\" * 55
\n" ); document.write( "2s = 27(5)
\n" ); document.write( "2s = 135
\n" ); document.write( "s = 67.5 mph to catch W in 2 hrs
\n" ); document.write( ";
\n" ); document.write( ":
\n" ); document.write( "Check solution by find the distances:
\n" ); document.write( "White's dist: 135 mi
\n" ); document.write( "Husband's dist: 2*67.5 = 135 mi also\r
