- What was the average number of flowers sold per hour from 13 00 to 18 00?
(a)
Total number of flowers sold = 86
Half the number of flowers sold
=
12 x 86
= 43
Time that the florist took to sell half the total number of flower: 14 00
(b)
Between 16 00 to 17 00, there was no flowers sold.
(c)
Number of flowers sold by 13 00 = 27
Number of flowers sold by 18 00 = 82
Duration from 13 00 to 18 00 = 5 h
Average number of flowers sold per hour from 13 00 to 18 00
= (82 - 27) ÷ 5
= 55 ÷ 5
= 11
Answer(s): (a) 14 00; (b) 16 00 to 17 00; (c) 11
