Kathy paid $14 for renting a kayak starting from 16 00. What would be the latest time she must return the kayak to the shop?
Amount that Kathy paid for all the additional
12 hours
= 14 - 6.50
= $7.50
Number of sets of additional
12 hours
= 7.50 ÷ 2.50
= 3
Total additional time that Kathy paid for
= 3 x
12= 1
12 h
Total time that Kathy paid for
= 1 + 1
12= 2

12 h after 16 00 = 18 30
Latest time that Kathy must return the kayak to the shop: 18 30
