Betty paid $13.50 for renting a scooter starting from 12 00. What would be the latest time she must return the scooter to the shop?
Amount that Betty paid for all the additional
12 hours
= 13.50 - 4.50
= $9
Number of sets of additional
12 hours
= 9 ÷ 1.50
= 6
Total additional time that Betty paid for
= 6 x
12= 3 h
Total time that Betty paid for
= 1 + 3
= 4 h
4 h after 12 00 = 16 00
Latest time that Betty must return the scooter to the shop: 16 00
Answer(s): 16 00
