- At what time had the florist sold one-third the total number of flowers sold that day?
- During which one-hour interval was there no flower sold? Give your answer in the following format (Eg 09 00 to 10 00)
- What was the average number of flowers sold per hour from 10 00 to 16 00?
(a)
Total number of flowers sold = 174
One-third the number of flowers sold
=
13 x 174
= 58
Time that the florist took to sell one-third the total number of flower: 12 00
(b)
Between 14 00 to 15 00, there was no flowers sold.
(c)
Number of flowers sold by 10 00 = 16
Number of flowers sold by 16 00 = 124
Duration from 10 00 to 16 00 = 6 h
Average number of flowers sold per hour from 10 00 to 16 00
= (124 - 16) ÷ 6
= 108 ÷ 5
= 18
Answer(s): (a) 12 00; (b) 14 00 to 15 00; (c) 18
