from 8 am till 11 am is three hours
\n" ); document.write( "the bike had a three hour head start at 14 mph 3*14=42 miles
\n" ); document.write( "as the bike is going 14 mph and the car at 45 from that point we need to calculate the gain on the bike.
\n" ); document.write( "The car is gaining 45-14 =31 mph.
\n" ); document.write( "So how long in minutes will it take the car to make up 42 at 31 mph
\n" ); document.write( "42/31*60 about 81 minutes after 11am or about 12:21 pm
