%282%2A40%29%2F%2855-40%29 = 80%2F15 = 5 1%2F3 hours = 5 hours and 20 minutes.

2*40 in the numerator is the distance for Ted been ahead at the moment the father started his move/travel.

55 - 40 = 15 in the denominator is their relative speed (which is the rate of decreasing the distance between them).

The remaining explanation is the formula Time = Distance%2FRate.

Solved.
