Solve Rational Equations · Exercise 60

Boating Ari can drive his boat 18 miles with the current in the same amount of time it takes to drive 10 miles against the current. If the speed of the boat is 7 knots, solve the equation $\frac{18}{7 + c} = \frac{10}{7 - c}$ for c to find the speed of the current.
