A runner's distance-time graph shows these points: 0 min = 0 m, 5 min = 1000 m, 8 min = 1000 m, 12 min = 3000 m, 14 min = 2000 m.
(a) Work out the runner's speed during the first running section (0 to 5 min) in m/s, correct to 2 decimal places.
(b) Describe what happens to the runner between 12 min and 14 min.
(c) Work out the total distance the runner travelled during the whole 14 minutes.
