The answer is 40 m.
To get the total distance the runner travels in 6 seconds, you must compute the average velocity first since the velocity of the runner changes from time to time.
Total of velocity divide by 4.
AV = 2 + 5 + 8 + 12 = 27
AV = 27 / 4
AV = 6.75
To get the distance, the formula is Distance = Average Velocity x Time:
D = 6.75 m/s x 6 sec
D = 40 m
