The second cyclist travels at 10 miles per hour and starts 3 hours after the first cyclist who is traveling at 6 miles per hour. How much time will pass before the second cyclist catches up with the first from the time the second cyclist started biking? \n" ); document.write( ": \n" ); document.write( "Let t = time the 2nd cyclist is on the road when he catches up \n" ); document.write( "Then (t+3) = time the 1st cyclist is on the road. \n" ); document.write( ": \n" ); document.write( "When the 2nd cyclist catches up with the 1st, we know they will have traveled the same distance. \n" ); document.write( ": \n" ); document.write( "Write a distance equation: Distance = speed * time \n" ); document.write( ": \n" ); document.write( "10t = 6(t+3) \n" ); document.write( "10t = 6t + 18 \n" ); document.write( "10t - 6t = 18 \n" ); document.write( "4t = 18 \n" ); document.write( "t = 18/4 \n" ); document.write( "t = 4.5 hrs (time of the 2nd cyclist: \n" ); document.write( ": \n" ); document.write( "Then the 1st cyclist time = 7.5 hrs \n" ); document.write( "Check to see if both traveled the same distance \n" ); document.write( "4.5(10) = 45 mi \n" ); document.write( "7.5(6) = 45 mi also \n" ); document.write( ": \n" ); document.write( "Make sense to you, not that hard, right? \n" ); document.write( " \n" ); document.write( " |
