An albatross and a crane were migrating from location X to location Y which were 576 km apart.
The albatross started its flight at 7 p.m. which was 105 minutes earlier than the crane.
It was also found that the albatross reached its destination 135 minutes later than the crane.
If the crane's average flying speed was 18 km/h, find the average flying speed of the albatross.
