Esther paid $34 for renting a kayak starting from 14 00. What would be the latest time she must return the kayak to the shop?
Amount that Esther paid for all the additional
12 hours
= 34 - 11.50
= $22.50
Number of sets of additional
12 hours
= 22.50 ÷ 4.50
= 5
Total additional time that Esther paid for
= 5 x
12= 2
12 h
Total time that Esther paid for
= 1 + 2
12= 3

12 h after 14 00 = 17 30
Latest time that Esther must return the kayak to the shop: 17 30
