You can put this solution on YOUR website!
In 1 hour Kate has traveled 80 km
That is the time when Juan leaves

every hour Kate is ahead by 8 km (80-72)
They have to be 98 km apart .
already she is 80 km apart when Juan leaves
98-80= 18 km
how much time will she take to be ahead by 18 km
18/8 = 2.25 hours
