we are given
A dripping faucet is wasting 0.5 mL of water every second
so, dropping rate is 0.5mL/seconds
[tex] r=0.5mL/sec [/tex]
we have to find amount of waste in 1 week
so, firstly we will find total time in seconds
1 week = 7 days
1 day =24 hours
1 hours =3600 seconds
now, we can change 1 week into seconds
we get
1 week = 7*24*3600 seconds
so, total time is 7*24*3600 sec
[tex] T=7*24*3600 [/tex]
total amount of water wastes = dropping rate * total time
[tex] w=r*T [/tex]
now, we can plug values
[tex] w=0.5*7*24*3600 mL [/tex]
[tex] w=302400 mL [/tex]
now, we can change into L
1 L =1000 mL
so, we get
[tex] w=302.4 L [/tex]
so, total water wastes in 1 week is 302.4 L.........Answer
