Please explain to me.

\fThe gure shows the velocity function for motion along a line. Assume the motion v(rru'sec) a begins with an initial position ofs{0}=1_ Determine the following. a. The displacement between t= U and t= 1i]. b. The distance traveled between I: U and t= 10. c. The position att=1l]. I ' cl. A piecewise function for s{t}. a. The displacement is D m. (Simplify your answer.)
