Roshel paid $21.50 for renting a scooter starting from 14 00. What would be the latest time she must return the scooter to the shop?
Amount that Roshel paid for all the additional
12 hours
= 21.50 - 7.50
= $14
Number of sets of additional
12 hours
= 14 ÷ 3.50
= 4
Total additional time that Roshel paid for
= 4 x
12= 2 h
Total time that Roshel paid for
= 1 + 2
= 3 h
3 h after 14 00 = 17 00
Latest time that Roshel must return the scooter to the shop: 17 00
Answer(s): 17 00
