If 
is the amount of salt in the tank at time 
, then the rate at which this amount changes over time is given by the ODE
We're told that the tank initially starts with no salt in the water, so
.
Multiply both sides by an integrating factor,
:
Since, we have
so that the amount of salt in the tank over time is given by
After 10 minutes, the amount of salt in the tank is
