Two cars start from rest at a traffic light and accelerate for several minutes. The AV graph shows their velocity (in feet per second) as a function of time (in seconds). Car A is the one that initially has greater velocity. Use the graph to answer parts a. through d. below. 30- Car B a. How far has car A traveled after 4.5 seconds? (Hint: Use formulas from geometry.) 45 feet b. When is car A farthest ahead of car B? 4.5 seconds 1.5 3 4.5 6 75 9 10.5 c. Estimate the farthest that car A gets ahead of car B. For car A, use formulas from geometry. For car B, use n = 3 and the value of the function at the midpoint of each interval. The farthest ahead car A gets is approximately | feet ahead of car B. (Round to one decimal place as needed.) d. Give a rough estimate of when car B catches up with car A. Choose the best estimate below. O A. Between t = 10.5 and t = 12 O B. Between t = 7.5 and t = 9 O C. Between t = 6 and t = 7.5 O D. Between t = 4.5 and t = 6
