"Rowanda 7.24 km and Terrance 5.1 km" is correct:
Rowanda jogged farther than Terrance so the third version, where 3.51km is smaller than 5.65km, can be ruled out. Then you have to look for the difference between the two values of the others--it has to be a difference of 2.14km. in this case it works:
7.24km - 5.1km = 2.14km
this shows she jogged 2.14km more than Terrance :)
The same thing works for the first version with 6.5km-4.36km=2.14km :) so the first one is correct, too
