a) 15cm^3
b) 8:16 am
1 liter = 1,000 cm cubic
Area A = 800
in 10 minutes
12 litters=12,000cm
12,000/800=15 cm
Tank A=15 cm ^3
Area B = 2,000
In 1 minute 5 liters = 5,000 cm^3
5,000/2000 = 2.5 cm^3 in 1 minute
To know how many minutes to reach 15:
15/2.5 = 6
6 minutes (from 8:10 am to 8:16 am)
5liters x 6 minutes =30 liters = 30,000 cm^3
30,000/2000 = 15 cm^3
