Natalie paid $57.50 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 Natalie paid for all the additional
12 hours
= 57.50 - 13.50
= $44
Number of sets of additional
12 hours
= 44 ÷ 5.50
= 8
Total additional time that Natalie paid for
= 8 x
12= 4 h
Total time that Natalie paid for
= 1 + 4
= 5 h
5 h after 15 00 = 20 00
Latest time that Natalie must return the paddle boat to the shop: 20 00
Answer(s): 20 00
