Differentiation — practice question

The speed-time graph provides details of a train journey. Speed is given in km/min and time is measured in minutes.

By drawing a suitable tangent to the graph, estimate the curve’s gradient at $t = 24$.

(b)[1]

What does this gradient indicate?

(c)[2]

Work out the distance travelled by the train while it is moving at constant speed.
