A canoeist heads north for 1.2km on a lake and then heads west for 1.8km. Her speed is steady at 5m/s.
a) How long does it take her?
b) What is her average velocity?
The Attempt at a Solution
Total of 600s but the answers suggested 0.60h
The average velocity was suggested as 3.6km/h or 1m/s but throughout her trip she held a constant speed of 5m/s.
So there is concern for the suggested answer for both a) and b)
