Emily paid $15.50 for renting a skateboard starting from 16 00. What would be the latest time she must return the skateboard to the shop?
Amount that Emily paid for all the additional
12 hours
= 15.50 - 5.50
= $10
Number of sets of additional
12 hours
= 10 ÷ 2.50
= 4
Total additional time that Emily paid for
= 4 x
12= 2 h
Total time that Emily paid for
= 1 + 2
= 3 h
3 h after 16 00 = 19 00
Latest time that Emily must return the skateboard to the shop: 19 00
Answer(s): 19 00
