Opal paid $14.50 for renting a bicycle starting from 16 00. What would be the latest time she must return the bicycle to the shop?
Amount that Opal paid for all the additional
12 hours
= 14.50 - 7.50
= $7
Number of sets of additional
12 hours
= 7 ÷ 3.50
= 2
Total additional time that Opal paid for
= 2 x
12= 1 h
Total time that Opal paid for
= 1 + 1
= 2 h
2 h after 16 00 = 18 00
Latest time that Opal must return the bicycle to the shop: 18 00
Answer(s): 18 00
