.
The rate on the way to the airport is r1 = D%2F1, where D is the distance, 1 = 1 hour.

The rate on the way back is r2 = D%2F%28%285%2F4%29%29 = %284D%29%2F5, where 5%2F4 = 1 hour 15 minutes.

The ratio of the rates is r2%2Fr1 = 4%2F5.


It is the answer to your question: her pace is 4%2F5 slower, or in 20% slower.

Solved.
