If the volume of the vase is V, then 20% of the water in the vase, represented by 0.20V, leaks out at the rate of 0.5 in^3. Our job is to calculate how long this takes.
quantity
Quantity = rate times time, so that (time) =
rate
0.20V
Then (time required for 20% of the water to leak out) =
0.5 in^3 per min
= 0.4V (we don't know V)
The time req'd for all of the water to leak out from a full vase is
(time) = 5(0.4V) = 2V minutes
22. so easy i think that’s it tell me i’m right
