Ken must jog with 12mph.That is because:from 7:30 to 8 is 30 minutes and Jenny started at 7o'clock and has to jog until 8 o'clock=>Jenny has to go 360 mhp and Ken must go 360mhp=> 30x=6.60=30x=360 x=360:30=12mph(that is the speed that Ken must go with) And 360mph is the whole distance!
That is from me
