Betty paid $24 for renting a bicycle starting from 12 00. What would be the latest time she must return the bicycle to the shop?
Amount that Betty paid for all the additional
12 hours
= 24 - 10.50
= $13.50
Number of sets of additional
12 hours
= 13.50 ÷ 4.50
= 3
Total additional time that Betty paid for
= 3 x
12= 1
12 h
Total time that Betty paid for
= 1 + 1
12= 2

12 h after 12 00 = 14 30
Latest time that Betty must return the bicycle to the shop: 14 30
