a rowing team rowed an average of 15.8 miles per hour with the current and 9.4 miles per hour against the current. Determine the team's rowing speed in still water and the speed of the current.
***
let x=rowing speed in still water
let c=speed of the current.
(x+c)=rowing speed of team with the current
(x-c)=rowing speed of team against the current
..
x+c=15.8
x-c=9.4
add
2x=25.2
x=12.6
c=x-9.4=3.2
rowing speed in still water=12 mph
speed of current=3.2 mph
