Xuan paid $33 for renting a paddle boat starting from 14 00. What would be the latest time she must return the paddle boat to the shop?
Amount that Xuan paid for all the additional
12 hours
= 33 - 8.50
= $24.50
Number of sets of additional
12 hours
= 24.50 ÷ 3.50
= 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
4
12 h after 14 00 = 18 30
Latest time that Xuan must return the paddle boat to the shop: 18 30
Answer(s): 18 30
