Suppose another oil tank with a hole in it takes three

days to leak 11gallons of oil. Assuming that the rate of

leakage at time t is given by r(t)=kt for some constant k,

set up and solve an equation involving a definite integral

to find k.

Short Answer

Expert verified

The rate is0.0042

Step by step solution

01

Step 1. Given information:An Oil tank takes thre days to leak 11 gallons of oil 

An expression for rate of leakage is given as r(t)=kt

02

Step 2. Finding rate

The integral for the given condition is ∫072ktdt=11

Now simplify the integral as,

∫072ktdt=11kt22072=11k(72)22=11k=0.0042
