Ivory paid $38.50 for renting a paddle boat starting from 12 00. What would be the latest time she must return the paddle boat to the shop?
Amount that Ivory paid for all the additional
12 hours
= 38.50 - 11.50
= $27
Number of sets of additional
12 hours
= 27 ÷ 4.50
= 6
Total additional time that Ivory paid for
= 6 x
12= 3 h
Total time that Ivory paid for
= 1 + 3
= 4 h
4 h after 12 00 = 16 00
Latest time that Ivory must return the paddle boat to the shop: 16 00
Answer(s): 16 00
