Question

A rowing team rowed an average of

15.4

miles per hour with the current and

8.2

miles per hour against the current. Determine the​ team's rowing speed in still water and the speed of the current.

Answer 1

s+c = 15.45

s-c = 8.2

add the above equations

2s = 22.65

divide by 2

s = 11.325 mph = speed of the rowing team in still water

c = 15.45-11.325 = 4.125 mph = the current speed = 4 1/8 mph
