The position of an object moving in a straight line, in miles, can be modeled by the function s(t), where t is measured in days. Selected values of s(t) are shown in the table below. Approximate the average position of the object over the interval [0, 10] using a right Riemann sum with 4 subintervals indicated by the table. You may use a calculator if necessary. t 0 2 4 7 10 s(t) 15 19 21 30 45
