asked • 04/10/22A motorboat traveling with the current went 35 mi in 3.5 h. Traveling against the
current, the boat went 12 mi in 3 h. Find the rate of the boat in calm water and the rate
of the current.

35 = (b + c)(3.5)
12 = (b - c)(2)
Can you expand and solve for either b oer c and answer?

Why not use RATES (that is: (b+c) = 35/3.5 and (b-c) = 12/3 ? The problem asks for the RATES (that is, b and c).04/10/22
