Thank you for the opportunity to help you with your question!

Downstream: Velocity  = 7.5 + 1.5 m/s = 9 m/s

Time for 250 m downstream displacement = 250/9 = 28 seconds

Upstream: Velocity = 7.5-1.5 m/s = 6 m/s

Time for 250 m upstream displacement = 250/6 = 42 seconds

Total time taken = 28 + 42 seconds = 70 seconds

Answer: Time = 70 seconds

Please let me know if you need any clarification. I'm always happy to answer your questions. Kindly best this answer if it has helped you.
