Question 411855
On a certain river, a motoboat can travel 34 miles per hour with the current and 28 miles per hour against the current. Find the speed of the motorboat in still water and the speed of the current.

boat speed = xmph
current speed = ymph
x+y =34
x-y=28
add the equations
2x=72
/2
x= 31 mph
y= 3 mph
