Some foreign tourists observed that a boat goes 30km upstream and 44km downstream in 10hrs. The
same boat goes 40km upstream & 55km downstream in 13hrs. By some instruments, they calculated the
speed of the boat in still water as 8.5km/h & speed of the stream as 3.8km/h. Do you agree with their
findings? Explain.
