By definition of conditional probability,

P(B | A) = P(A ∩ B)/P(A) = (13/25) / (13/20) = 20/25 = 4/5

So if Katrina did 80mph and

Mia did 60mph

Lets say the destination is 90 miles away that would take 1hr 30minsfor Mia and

1hr 10mins for Katrina. so that's only a gap of 20minutes not half an hour.

So if the destination was 120miles away it would take Mia 2 hours and Katrina 1hour 30mins that is a gap of 30mins.

ANSWER: 120miles
