Xandra paid $35.50 for renting a paddle boat starting from 15 00. What would be the latest time she must return the paddle boat to the shop?
Amount that Xandra paid for all the additional
12 hours
= 35.50 - 13.50
= $22
Number of sets of additional
12 hours
= 22 ÷ 5.50
= 4
Total additional time that Xandra paid for
= 4 x
12= 2 h
Total time that Xandra paid for
= 1 + 2
= 3 h
3 h after 15 00 = 18 00
Latest time that Xandra must return the paddle boat to the shop: 18 00
Answer(s): 18 00
