[QUOTE="David J, post: 6095351, member: 562210"] [I]Not wrong t is the elapsed time which is 2.55 seconds for one unit change. The question is asking for the time taken for the output to change by 4 units so 2.55*4=... You then have to create a graph. I created a graph with an x-axis of 5 units and a y-axis of 12 units. I plotted a line from (y=2, x=0) to (y=2, x=2). We are told the step change occurred from 2 units to 12 units so from 0 units to 2 units nothing happened, it flat lined so to speak. It then jumped by 10 units so i plotted a line from (y=2, x=2) to (y=12, x=4). There is a right angle triangle created here and the answer your trying to verify is the length of the hypotenuse. If you plot the graph then use square root (adjacent^2 + opposite^2) it gives you a very close answer to the one you proved using the math. I spent ages on this one and I wasn't convinced my answer was right after reading other posts but I submitted it anyway and was told it was correct[/I] [/QUOTE]
