Xuan paid $42 for renting a canoe starting from 13 00. What would be the latest time she must return the canoe to the shop?
Amount that Xuan paid for all the additional
12 hours
= 42 - 10.50
= $31.50
Number of sets of additional
12 hours
= 31.50 ÷ 4.50
= 7
Total additional time that Xuan paid for
= 7 x
12= 3
12 h
Total time that Xuan paid for
= 1 + 3
12= 4
12 h

12 h after 13 00 = 17 30
Latest time that Xuan must return the canoe to the shop: 17 30
