7. Solve eq2 for b to calculate the actual
speed of the boat.
solve(eq2,b)
8. Substitute the known value of b into eq1,
and solve
eq1 for a to determine a, the
speed of the eastward traveling current.
solve(eq1,a) | b
The boat travels at a speed of 22.7 knots, and
the water current is approximately 7.9 knots.
