Question 267817
Flo is pedalboating on the river. 
Going downstream their speed is 40 m/min. 
Coming back upstream their speed is only 26 m/min.
-----------------------
Equations:
boat + current = 40 m/min
boat - current = 26 m/min
-------------------------------
2b = 66 m/min
boat speed  = 33 m/min
---
Substitute and solve for current:
33 + current = 40
current = 7 m/min
---------------------------

How fast do they move through water? 
How fast is the current going?
