Irene paid $14 for renting a bicycle starting from 17 00. What would be the latest time she must return the bicycle to the shop?
Amount that Irene paid for all the additional
12 hours
= 14 - 3.50
= $10.50
Number of sets of additional
12 hours
= 10.50 ÷ 1.50
= 7
Total additional time that Irene paid for
= 7 x
12= 3
12 h
Total time that Irene paid for
= 1 + 3
12= 4
12 h
4
12 h after 17 00 = 21 30
Latest time that Irene must return the bicycle to the shop: 21 30
Answer(s): 21 30
