Suppose you want to spend 4 hours rowing down the river 16 miles, but 8 hours rowing back up the river. How fast were you rowing? How fast is the river flowing? How could you use systems of equations to solve the problem?
A.
Let x = your rowing speed.
Let y = the river current speed.
4(x - y) = 16
8(x + y) = 16
x = 4 miles per hour for rowing your boat
y = 2 mile per hour for the river current
B.
Let x = your rowing speed.
Let y = the river current speed.
x + y = 4
x - y = 8
x = 6 miles per hour for rowing your boat
y = 2 miles per hour for the river current
C.
Let x = your rowing speed.
Let y = the river current speed.
4(x + y) = 16
8(x - y) = 16
x = 3 miles per hour for rowing your boat
y = 1 mile per hour for the river current
D.
Let x = your rowing speed.
Let y = the river current speed.
16 (x + y) = 4
1/16(x - y) = 8
x = 96 miles per hour for rowing your boat
y = 32 miles per hour for the river current
