The speed of a runner increased steadily during the first three seconds of a race. Her speed at half-second intervals is given in the table. Find lower and upper estimates for the distance that she traveled during these three seconds. t (s) 0 0.5 1.0 1.5 2.0 2.5 3.0 v (ft/s) 06.2 10.8 14.9 18.1 19.4 20.2 Step 1 We will use either L6 or R6 for the upper and lower estimates. Since the runner's speed is an increasing function, then 0 X will give the lower estimate, and 45.1 X will give the upper estimate.
