Answer:
168.6777 cm
Step-by-step explanation:
Mean height of 10 runners = 166.8
Total height of the 10 runners = 166.8 x 10 = 1688 cm
Height of tallest person = 169.9 cm
Difference between total height and height of tallest person = 1688 - 169.9 = 1518.1
Mean height of the remaining 9 runners = 1518.1 / 9 = 168.6777
