Question 1095020: The time t required to empty a wastewater-holding tank is inversely proportional to the sectional area A. If it takes 2.0 hours to empty a tank with a drainage pipe of A = 48in^2, how long will it take to empty a tank with A = 68in^2

Use a constant of proportionality, +k+
+t+=+k%2A%28+1%2FA+%29+
+2+=+k%2A%28+1%2F48+%29+
+k+=+96+
------------------
+t+=+k%2A%28+1%2F68+%29+
+t+=+96%2A%28+1%2F68+%29+
+t+=+1.412+ hrs
