Answer:
The number of cars passing or the people arriving during lunch hour will be around 220
Explanation:
First we find the for ten minutes period from given data:
Average Cars in 10 minutes = (18+38+87+16+56+5)/6
Average Cars minutes = 36.67
Now, for average cars in 1 hr, we must multiply this value by 6. As, 10 minutes multiplied by 6 equals 1 hr.
Average cars in an hour = 36.67*6
Average Cars in an hour = 220
Hence, the number of cars or people arriving during lunch hour will also be equal to average number of cars arriving during an hour.
