PSLE The table shows the charges for bicycle rental. Justin rented a bicycle from 11.25 a.m. to 5.45 p.m.. How much did he pay?
Bicycle rental |
Charges |
First hour |
$4 |
Additional 12 hour or part thereof |
$1.80 |
From 11.25 a.m. to 12.25 p.m. = 1 h
From 12.25 p.m. to 5.45 p.m. = 5 h 20 min = 320 min
Sets of additional
12 hour
= 320 ÷ 30
= 10 r 20
Total number of sets of additional
12 hour and part thereof to pay for
= 10 + 1
= 11
Amount to pay from 11.25 a.m. to 12.25 a.m. = $4
Amount to pay from 12.25 a.m. to 5.45 p.m. = 11 x 1.80 = $19.80
Total amount that Justin paid
= 4 + 19.80
= $23.80
Answer(s): $23.80
