# Question

A speedboat can travel with a speed of 50 m/s in still water. If the boat is in a river that has a flow speed of 5.0 m/s,

(a) Find the maximum and minimum values of the boat’s speed relative to an observer on the riverbank.

(b) What is the time difference between a downriver trip (with the current) of 1000 m and an upriver trip (against the current)?
