 
 <prompt> "Theon's ship can move 15 nautical miles per hour while Yara's ship can move 30 nautical miles per hour. If their destination is 90 nautical miles away, how many hours ahead will Yara be ahead of Theon?" 

```Yara's ship le le 15 nautical miles ni isale kan ni awon ago pelu Yara le le 30 nautical miles ni isale kan ni awon ago. Ti awon agogo won ni 90 nautical miles ni ibeere, ni ojo meji Yara yio de Theon?"``` <response>: "Theon's estimated time of arrival is 90/15 = 6 hours.
Yara's estimated time of arrival is 90/30 = 3 hours.
Therefore, Yara is ahead by 6 - 3 = 3 hours.

The answer will be 3."
