Ivory paid $16.50 for renting a scooter starting from 14 00. What would be the latest time she must return the scooter to the shop?
Amount that Ivory paid for all the additional
12 hours
= 16.50 - 4.50
= $12
Number of sets of additional
12 hours
= 12 ÷ 1.50
= 8
Total additional time that Ivory paid for
= 8 x
12= 4 h
Total time that Ivory paid for
= 1 + 4
= 5 h
5 h after 14 00 = 19 00
Latest time that Ivory must return the scooter to the shop: 19 00
Answer(s): 19 00
