A speed‑time graph for a car shows the following: from \(t = 0\) to \(t = 2\) h the speed increases uniformly from 0 to 60 \(km/h\); from \(t = 2\) h to \(t = 5\) h the speed remains constant at 60 \(km/h\); from \(t = 5\) h to \(t = 6\) h the speed decreases uniformly to 0 \(km/h\). (a) Calculate the total distance travelled in the 6‑hour period. (b) At what time does the car first reach a speed of 45 \(km/h\)? Give your answer in hours.

Answer Options

A. Total \(distance = 280\) km; \(time = 1.8\) h
B. Total \(distance = 270\) km; \(time = 2.0\) h
C. Total \(distance = 260\) km; \(time = 1.2\) h
Correct Answer D. Total \(distance = 270\) km; \(time = 1.5\) h
Correct Answer
D
Correct Option:
Total \(distance = 270\) km; \(time = 1.5\) h
