Mary paid $12 for renting a scooter starting from 16 00. What would be the latest time she must return the scooter to the shop?
Amount that Mary paid for all the additional
12 hours
= 12 - 4.50
= $7.50
Number of sets of additional
12 hours
= 7.50 ÷ 1.50
= 5
Total additional time that Mary paid for
= 5 x
12= 2
12 h
Total time that Mary paid for
= 1 + 2
12= 3

12 h after 16 00 = 19 30
Latest time that Mary must return the scooter to the shop: 19 30
