15.A hiker's distance from the start of the trail, in kilometres, is plotted against time, in minutes, since she set off. At t = 45 minutes she stops to rest, so her distance from the start is neither increasing nor decreasing at that instant. Which statement about the tangent to the distance–time graph at t = 45 minutes is correct?
(a)The gradient equals 45, the time in minutes she stops.
(b)The tangent is vertical, so its gradient is undefined.
(c)The tangent is horizontal, so its gradient is 0.
(d)The gradient can't be found without her distance too.
