Lucy paid $34.50 for renting a bicycle starting from 15 00. What would be the latest time she must return the bicycle to the shop?
Amount that Lucy paid for all the additional
12 hours
= 34.50 - 12.50
= $22
Number of sets of additional
12 hours
= 22 ÷ 5.50
= 4
Total additional time that Lucy paid for
= 4 x
12= 2 h
Total time that Lucy paid for
= 1 + 2
= 3 h
3 h after 15 00 = 18 00
Latest time that Lucy must return the bicycle to the shop: 18 00
Answer(s): 18 00
