An object has a velocity v(t) = 2 t + 55 ft/s. use the interval [2, 14] with n = 6 and equal subintervals to compute the following approximations of the distance the object traveled. (round your final answers to two decimal place.)
(a) left-hand sum = ft
(b) right-hand sum = ft
(c) average of the two sums = ft
