Question 177645
<FONT FACE="Times New Roman" SIZE="+2">The trick here is to recognize that you are dealing with a relative motion problem.  The answer would be the same if one of them was going 98 miles per hour and the other one 100 mph -- or more to the point, if Janet stood still and Ryan went 2 mph.  So, how long would it take Ryan to go half a mile at 2 mph?</FONT>
