Compare the values of the two quantities in the question and answer. Quantity 1: A boat takes 3 hrs. 20 min. to travel 40 km upstream and 2 hrs.40 min. to travel the same distance in still water. How much time will it take to cover the same distance downstream? Quantity 2: The downstream speed of a boat is 22 km/hr and upstream speed is 17 km/hr. How much time will it take to travel 45 km in still water?
