Russ and Janet are running. Russ runs at 7mph, Janet at 5mph. If the run has a staggered start, and Janet starts first with Russ starting 10 minutes later, how long before he catches up with her?\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Step 1. Find distance Janet travels just before Russ starts running.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "(5 miles/hour) * (1 hour/60 minutes) * (10 minutes) = \"5%2A10%2F60=5%2F6\" miles\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Step 2. You need to realize that Russ and Janet must travel the same distance when Russ catches up.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "distance = velocity * time\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Step 3. Russ traveled \"7%2Ax\" where x is the time (in hours) he traveled\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Step 4. Janet traveled \"5%2F6%2B5%2Ax\" where same x is the time she traveled\r
\n" ); document.write( "\n" ); document.write( "Step 5. Set equations equal: Step 3 = Step 4\r
\n" ); document.write( "\n" ); document.write( "\"7%2Ax=5%2F6%2B5%2Ax\"\r
\n" ); document.write( "\n" ); document.write( "Step 6. Subtract 5x from both sides of equation in previous step.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"7x-5x=5%2F6%2B5x-5x\"\r
\n" ); document.write( "\n" ); document.write( "\"2x=5%2F6\"\r
\n" ); document.write( "\n" ); document.write( "Step 7. Divide by 2 to solve for x\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"2x%2F2=5%2F%282%2A6%29\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Step 8. Answer is \r
\n" ); document.write( "\n" ); document.write( "\"x=5%2F12\" hour or \"x=5%2F12%2A60=25\" minutes where 60 minutes = 1 hour\r
