Irene paid $33.50 for renting a kayak starting from 14 00. What would be the latest time she must return the kayak to the shop?
Amount that Irene paid for all the additional
12 hours
= 33.50 - 11.50
= $22
Number of sets of additional
12 hours
= 22 ÷ 5.50
= 4
Total additional time that Irene paid for
= 4 x
12= 2 h
Total time that Irene paid for
= 1 + 2
= 3 h
3 h after 14 00 = 17 00
Latest time that Irene must return the kayak to the shop: 17 00
Answer(s): 17 00
