a man jogged to his friend's house at a rate of 6 mph. the trip took 20 minutes.
\n" ); document.write( " how long will it take him to return home if he can maintain a rate of 8 mph?
\n" ); document.write( ":
\n" ); document.write( "Let t = time required in min to return home
\n" ); document.write( ":
\n" ); document.write( "We don't have to convert to mph here
\n" ); document.write( "6*20 = 8t
\n" ); document.write( "120 = 8t
\n" ); document.write( "t = 120/8
\n" ); document.write( "t = 15 min to return
\n" ); document.write( ":
\n" ); document.write( "Find the dist in mi by using hrs to check it:
\n" ); document.write( "6mph * $\"1%2F3\"$ hr = 2 mi
\n" ); document.write( "8mph * $\"1%2F4\"$ hr = 2 mi \n" ); document.write( "
