ECZ 2016 · O-Level Paper 1 — Travel Graphs
The distance travelled by the particle from 0 to 20 seconds is 80 m. Find the value of v.
- A. 4⁄3 m/s
- B. 4 m/s
- C. 8⁄3 m/s
- D. 2⁄3 m/s
Verified working — step 1
Distance = area of trapezium = ½(v + 5v)(20) = 60v. So 60v = 80, giving v = 80⁄60 = …The full step-by-step working and final answer are included with Premium — checked against ECZ marking standards.
