Chapter 6.2, Problem 33E

Area between velocity curves Two runners, starting at the same location, run along a straight road for 1 hour. The velocity of ore runner is v₁(t) – 7t and the velocity of the other rurner is $v_2\left(t\right)-10\sqrt{t}$. Assume t is measured in hou'S and the veocities v₁(t) and v₂(t) are measured in km/hr. Determine the area between the curves y = v₁ (l) and y = v₂(l), for 0 < l < 1. Interpret the physical meaning of this area
