Xuan paid $16.50 for renting a bicycle starting from 13 00. What would be the latest time she must return the bicycle to the shop?
Amount that Xuan paid for all the additional
12 hours
= 16.50 - 9.50
= $7
Number of sets of additional
12 hours
= 7 ÷ 3.50
= 2
Total additional time that Xuan paid for
= 2 x
12= 1 h
Total time that Xuan paid for
= 1 + 1
= 2 h
2 h after 13 00 = 15 00
Latest time that Xuan must return the bicycle to the shop: 15 00
Answer(s): 15 00
