Question
Seth and Oscar started on a 55-km cycling trip at the same time. They cycled at the same speed for first 10 km. For the remaining 45 km, Seth cycled faster than Oscar. He arrived at the finishing point 24 minutes before Oscar who was 10 km behind him. Oscar did not change his speed throughout and completed it at 08 25.
At what time did the trip begin? Give the answer in 12-hour format.
What was Seth's average speed for the remaining 45 km of the trip in km/h?
