25 points..

Explain with process.....​

Answer 1

Answer:

To find the distance travelled first graph the parabola. Youll find its vertices to be (3,24).

At t=3, s=24. At t=0, s=6. The distance travelled between t=0 to t=3 is d1 = 24-6 = 18m

At t=5, s=16. 16 is the DISPLACEMENT. The distance travelled from t=3 to t=5 is d2 = 24 - 16 = 8m

Therefore the total distance travelled is

D = d1 + d2

D = 18 + 8 = 26m

So option (d) is right.
