whats needed?

OpenStudy (anonymous):

i need help solving the question in the link

OpenStudy (anonymous):

or at least help with setting up the equations

OpenStudy (anonymous):

can you type the problem into the comments real quick?

OpenStudy (michele_laino):

your problem can be modeled by these 2 subsequent equations: plane A altitude = 2353+ 35.25*t, t is time in seconds plane B: altitude= 80.5*t, t is time in seconds

OpenStudy (michele_laino):

now there is a time t_0, such that those altitudes are equals each other. The time t_0 is given by the subsequent equation: \[\Large 2353 + 35.25{t_0} = 80.5{t_0}\] what is t_0?

OpenStudy (anonymous):

Plane A : F(x)=35.25a+2353 Plane B : F(x)=80.5a+0 A=Altitude

OpenStudy (anonymous):

im not sure what t0 is

OpenStudy (anonymous):

waait i figured it out thankyou guys

OpenStudy (anonymous):

it was 52 and 4186

OpenStudy (michele_laino):
