Shiyun paid $39 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 Shiyun 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 Shiyun paid for
= 5 x
12= 2
12 h
Total time that Shiyun paid for
= 1 + 2
12= 3
12 h

12 h after 14 00 = 17 30
Latest time that Shiyun must return the paddle boat to the shop: 17 30
Answer(s): 17 30
