A rowing team is practicing on a river. When the boat travels downstream, the current increases the speed of the boat. But when the boat travels upstream, the current decreases the speed of the boat. The team wrote a system letting s represent the speed in calm water and c represent the speed of the current. They found the solution for the system (s, c) to be (14, 6). How fast was the team traveling upstream and downstream?A. The team traveled at 6 km per hour upstream and 14 km per hour downstream.B. The team traveled at 14 km per hour upstream and 6 km per hour downstream.C. The team traveled at 8 km per hour upstream and 20 km per hour downstream.D. The team traveled at 20 km per hour upstream and 8 km per hour downstream.
