RuizRecitation Activity 1Instructions: Please work in small groups (3 or 4 students) on the following problems. You are expected to finish these problems even if there was not enough time in class to finish.(1) The following is a graph of the velocity of a car accelerating from cont to xpace of 1200ckmh bere apetiod of 30 seconds.(a) Draw and shade in the rectangles needed to represent a left sum approximation of the distance traveled on the interval (0,30) with =6 rectangles.(b) Use the graph to estimate the distance traveled on the interval {0,30} with a left Riemann sum with n=6 rectangles. Note: 1 second is equal to 1500 hours.(c) Does this give an overestimate or an underestimate of the distance traveled?underestimate(d) Interpret the Riemann Sum in the context of the situation. Include units in your answer.L6=5*0 1
