Calculate the distance travelled using a speed-time graph Here is a speed-time graph for a car.

Which of the following gives the best estimate for the distance travelled between \( 8 \) and \( 10 \) seconds? ![A graph showing time in seconds on the x axis and speed in metres per second on the y axis. The curve passes through the points (8,15) and (10,24)]() \( 48 m \)
