Find a solution to dA/dt=-6A if A(0)=6. A(t)=
Delicious77 [7]

This equation is separable,

\dfrac{dA}{dt} = -6A \implies \dfrac{dA}A = -6\,dt

Integrate both sides and solve for A :

\displaystyle \int \frac{dA}A = -6 \int dt

\ln|A| = -6t + C

e^{\ln|A|} + e^{-6t+C}

\implies A(t) = Ce^{-6t}

Solve for C using the initial value.

A(0) = 6 \implies 6 = Ce^0 \implies C=6

Then the particular solution is

\boxed{A(t) = 6e^{-6t}}

It took Max 3.5 hours to cover a certain route walking at a rate of 2.4 mph. How long would it take Max to cover the same route
andrew11 [14]
It would take 2.8 hours ((3.5 hours x 2.4 Mph)/3Mph) hours for Max to cover the same route walking 3 mph. This problem can be solved by using the velocity equation which is the velocity is equal a change in position divided by a change of time. The amount of time can be found assuming that Max walks in a constant velocity from the starting point until the finish point of 8.4 miles distance (3.5 hours x 2.4 mph)<span>.</span>
