don --- speed = 6kmph
jane speed = 10 kmph
Catch up speed = 10-6 =4 kmph
catch up distance = 10 km
catch up time = catch distance/catch up rate
time = 10/4
time = 2.5 hours

Jane is gaining on Don at 4 kph
so how long will it take to go 10 k at 4 kph
10/4=2.5 hours
so we start out with don 10 miles
after an hour don has gone another 6 miles
so it at the 1 k marker
jane is at the 10 k marker
after another hour
don is at the 22 k marker
jane is at the 20 k marker
in half an hour more don goes 3 k
and jane goes 5 k
They meet at the 25 k marker
