A family is canoeing downstream (with the current). Their speed relative to the banks of the river averages 2.75 mi/h. During the return trip, they paddle upstream (against the current), averaging 1.5 mi/h relative to the riverbank. Write and solve a system of equations to find the family’s paddling speed in still water. Let s equal the families paddling speed and c represent the current a. s + c = 2.75 s - c = 1.5 2.125 mi/h c. s + c = 2.75 c - s = 1.5 .60 mi/h b. 2.75s = c 1.5s = c 1.725 mi/h d. 2.75c = s 1.5c = s 30 mi/h Please select the best answer from the choices provided
