As found earlier, the rate at which the water drains is given by V'(t) = -240(1 - 1/50t) When t = 10, the rate at which the water drains is, therefore, V'(10) = gal/min.

Step 1
V'(10) = -240(1 - 1/50(10)) V'(10) = -240(1 - 1/5) V'(10) = -240(1 - 0.2) V'(10) = -240(0.8) V'(10) = -192 Show more…

A 1000 L tank is draining such that the volume V of water remaining in the tank after t minutes is V equals 1000 times quantity (1- t/60)^2 Find the rate at which the water is flowing out of the tank after 10 min.

If a tank holds 1000 L of water, which takes an hour to drain from the bottom of the tank, then the volume V of water remaining in the tank after t minutes is V = 1000 (1 - t/60)^2 when 0 ≤ t ≤ 60. Find the rate at which the water is flowing out of the tank (the instantaneous rate of change of V with respect to t) after 10 minutes. ... Please do not use derivatives to solve.

Water is drained from a swimming pool at a rate given by $R(t)=100 e^{-0.05 t}$ gal $/ \mathrm{hr} .$ If the drain is left open indefinitely, how much water drains from the pool?
