Sarah paid $15.50 for renting a scooter starting from 14 00. What would be the latest time she must return the scooter to the shop?
Amount that Sarah paid for all the additional
12 hours
= 15.50 - 3.50
= $12
Number of sets of additional
12 hours
= 12 ÷ 1.50
= 8
Total additional time that Sarah paid for
= 8 x
12= 4 h
Total time that Sarah paid for
= 1 + 4
= 5 h
5 h after 14 00 = 19 00
Latest time that Sarah must return the scooter to the shop: 19 00
Answer(s): 19 00
