A table of values for the velocity, v(t), of a car traveling on a straight road, for 0 St 50, is shown above. v(t) is measured in feet per second and time t is measured in seconds. Approximate the distance that the car has travelled using a trapezoidal Riemann sum with four subintervals. Include units in your answer. 1.
