12. a race car is running practice laps in preparation for an upcoming race. to judge how the car is performing, the crew takes measurements of the car’s speed s(t) (in miles per hour, or mph) every minute. the measurements are given in the table below. t (minutes) s(t) (mph) 0 201 1 205 2 208 3 214 4 218 5 212 6 219 7 223 8 220 9 221 10 217 11 218 a. use the trapezoid rule with 4 equal subdivisions to approximate the total distance the car traveled (in miles) over the first 12 minutes. b. find one approximation for sv(6), including the units. explain what this quantity means in the context of the problem. c. what was the car’s average speed in mph over the first 12 minutes? if the car needs to have an average speed of 210 mph to qualify for the race, is it currently running fast enough to qualify?
