- What was the average number of flowers sold per hour from 11 00 to 17 00?
(a)
Total number of flowers sold = 174
Half the number of flowers sold

(b)
Between 15 00 to 16 00, there was no flowers sold.
(c)
Number of flowers sold by 11 00 = 52

Duration from 11 00 to 17 00 = 6 h
Average number of flowers sold per hour from 11 00 to 17 00
= (154 - 52) ÷ 6
= 102 ÷ 5
= 17
