Problem: A Nile cruise ship takes 23.7 h to go upstream from Luxor to Aswan, a distance of 207 km, and 22.2 h to make the return trip downstream. Assuming the ship's speed relative to the water is the same in both cases,
Part A: Calculate the speed of the current in the Nile.
Please show how you obtained the speed of the current in the Nile.
