Question 516032: At noon, Sheila left a boat landing and paddled her canoe 20 km downstream and 20 km back. If she traveled 10km/h downstream and 4km/h upstream what time did she arrive at the landing?? Answer by Alan3354(69443) (Show Source):
You can put this solution on YOUR website! Avg speed = 2*10*4/(10+4) = 40/7 km/hr
40 km roundtrip at 40/7 km/hr takes 7 hours
Noon + 7 = 1900
