Angelo kayaks 20 km upstream in 3 hr and returns in 1.5 hr. How fast is the stream flowing and how fast does Angelo paddle in still water?
-
x – speed of Angelo
y – speed of the stream
Equations:
20 km = (x - y) 3 h
20 km = (x + y) 1.5 h
Solution:
x = 10 km/h
y = 3.333 km/h
-
y – speed of the stream
Equations:
20 km = (x - y) 3 h
20 km = (x + y) 1.5 h
Solution:
x = 10 km/h
y = 3.333 km/h
