Olivia paid $39 for renting a canoe starting from 14 00. What would be the latest time she must return the canoe to the shop?
Amount that Olivia paid for all the additional
12 hours
= 39 - 11.50
= $27.50
Number of sets of additional
12 hours
= 27.50 ÷ 5.50
= 5
Total additional time that Olivia paid for
= 5 x
12= 2
12 h
Total time that Olivia paid for
= 1 + 2
12= 3

12 h after 14 00 = 17 30
Latest time that Olivia must return the canoe to the shop: 17 30
