Kathy paid $37.50 for renting a bicycle starting from 17 00. What would be the latest time she must return the bicycle to the shop?
Amount that Kathy paid for all the additional
12 hours
= 37.50 - 9.50
= $28
Number of sets of additional
12 hours
= 28 ÷ 3.50
= 8
Total additional time that Kathy paid for
= 8 x
12= 4 h
Total time that Kathy paid for
= 1 + 4
= 5 h
5 h after 17 00 = 22 00
Latest time that Kathy must return the bicycle to the shop: 22 00
Answer(s): 22 00
