Tina 45 mph
leaves 3 hours early
so when Tim starts she is 45 * 3 = 135 miles ahead.
...
Tim speed = 65mph
..
the catch up speed = 65-45 20 mph
catch up distance = 135 miles
Time taken by Tim to catch up = 135/20 = 6.75 hours
..
Tim speed = 65 mph
time catch up = 6.75 hours
Distance he meets = 6.75 * 65=438.7 km
