Risa paid $20 for renting a canoe starting from 16 00. What would be the latest time she must return the canoe to the shop?
Amount that Risa paid for all the additional
12 hours
= 20 - 7.50
= $12.50
Number of sets of additional
12 hours
= 12.50 ÷ 2.50
= 5
Total additional time that Risa paid for
= 5 x
12= 2
12 h
Total time that Risa paid for
= 1 + 2
12= 3

12 h after 16 00 = 19 30
Latest time that Risa must return the canoe to the shop: 19 30
Answer(s): 19 30
