Elyse paid $28.50 for renting a canoe starting from 14 00. What would be the latest time she must return the canoe to the shop?
Amount that Elyse paid for all the additional
12 hours
= 28.50 - 7.50
= $21
Number of sets of additional
12 hours
= 21 ÷ 3.50
= 6
Total additional time that Elyse paid for
= 6 x
12= 3 h
Total time that Elyse paid for
= 1 + 3
= 4 h
4 h after 14 00 = 18 00
Latest time that Elyse must return the canoe to the shop: 18 00
Answer(s): 18 00
