A motor boat travels 752 km in 8 hrs going upstream and 1134 km.What is the speed of the boat in still wat?

Question

please I need help with this q

Answer 1

assuming the 1134 km is downstream for 8 hours, the speed of the boat will be the average ie  (752 + 1134)/(8+8) [ ie total distance divided by total time] equals 117.875 km/hr

If this is a real life question that's a pretty fast river (23.875 km/hr)

Answer 2

If you're looking for confirmation, the last answer was correct. Assuming there is no wind of course! I know, I've worked at sea for 27 years.
