5k^2(-6k-2k+6) i think you typed this wrong, or maybe one of the options. Expanded it is -30k^3 -10k^3+30k^2 simplified it is -40k^3+30k^2

would the answer be approx. 9.4557m/s? cz on the document it says the answer should be 4.68m/s

It is +3 because of he | | surrounding the 2x-3. the | | mean absolute, anything in between the | | will result in a positive number.

average velocity= delta position/time or displacement/time
