\n" ); document.write( "When Michelle starts her journey, Tim has driven for 48 minutes or 4/5 of an hour at 75 km/h; the distance he has traveled is (4/5)(75) = 60 kilometers. Michelle must make up that distance of 60 km to catch up with Tim.

\n" ); document.write( "When both are driving, Tim at 75 km/h and Michelle at 95 km/h, Michelle is catching up with Tim at a rate of (95-75) = 20 km/h. The number of hours it takes her to catch up is then 60/20 = 3.

\n" ); document.write( "ANSWER to the first question: It takes Michelle 3 hours to catch up with Tim.

\n" ); document.write( "When Michelle catches up with Tim, she has been driving for 3 hours at 95 km/h, covering a distance of 3*95 = 285 km. That is the total distance from A to B, so Michelle catches up to Tim at the time both of them reach B.

\n" ); document.write( "ANSWER to the second question: Tim is 0 km from B when Michelle completes her journey.
