A Return Car Journey

A driver makes a journey and returns by a different route. The speeds for the outward and return journies were different, but both averaged between 50 and 60 mph, taking between 2 and 3 hours each way. All speeds are odd integers, and the times are exact odd numbers of minutes. By coincidence, total mileage turns out be 300 exactly. Find both speeds and times.
