Barbara paid $19.50 for renting a bicycle starting from 12 00. What would be the latest time she must return the bicycle to the shop?
Amount that Barbara paid for all the additional
12 hours
= 19.50 - 10.50
= $9
Number of sets of additional
12 hours
= 9 ÷ 4.50
= 2
Total additional time that Barbara paid for
= 2 x
12= 1 h
Total time that Barbara paid for
= 1 + 1
= 2 h
2 h after 12 00 = 14 00
Latest time that Barbara must return the bicycle to the shop: 14 00
Answer(s): 14 00
