Xuan paid $15.50 for renting a scooter starting from 17 00. What would be the latest time she must return the scooter to the shop?
Amount that Xuan paid for all the additional
12 hours
= 15.50 - 8.50
= $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 17 00 = 19 00
Latest time that Xuan must return the scooter to the shop: 19 00
Answer(s): 19 00
