Racing cars driven by Chris and Kelly are side by side at the start of a race. The table shows the velocities of each car (in miles per hour) during the first ten seconds of the race. t VcVK 00 0 1 21 22 222 67 t VC VK 68 79 74 85 2 31 31 35 8 81 93 3 47 47 53 6 86 98 4 54 5 61 09 60 10 91 103 69 69 Use the midpoint rule to estimate how much farther (in mi) Kelly travels than Chris does during the first ten seconds. (Round your answer to four decimal places.)
