The diagram below shows the speed-time graph of an object. The object accelerates uniformly from O to P until it reaches a speed of 20 m/s in 4 seconds and then moves steadily from P to Q for 6 seconds and finally comes to rest. Find the total distance covered by the object.
- A. 300 m
- B. 200 m
- C. 170 m
- D. 210 m
