The units are meters. Are meters. All right. Then they say approximate the value of that integral using a right Riemann sum with the four subintervals indicated in the table. So what do they mean by a right Riemann sum? Well, actually, let me just draw, let me draw the absolute value of v of t, and I already took the trouble in the last part of drawing the axes, and you wouldn't actually have to do this on the test, but I'm doing this to just help you understand what we're actually going to do when we talk about a right Riemann sum. So in orange, I have v of t, but if I were to do the absolute value of v of t, I'll do that in magenta.
