Answer:

3.5 hours

Step-by-step explanation:

Ediburgh -------------------------------350 miles-------------------------London

Let the distance traveled by train from Edin to London be "x"

hence the distance traveled by train from London to Edin would be "350-x"

  • The rate of Edin to London train is 60
  • The rate of London to Edin train is 40

Let the time they meet be"t"

Now, we know distance formula to be D = RT

Where

D is distance

R is rate

and

T is time

<u>Train from Edin to London:</u>

x = 60t

<u>Train from London to Edin:</u>

350-x = 40t

Solving for x:

350 - 40t = x

We put this into first equation:

x = 60t

350 - 40t = 60t

350 = 100t

t = 350/100

t = 3.5

They meet after 3.5 hours

Step-by-step explanation:

<u>Step 1:  Distribute the plus</u>

(-4y^3 – 5y +16) + (4y^2 – y + 9)

-4y^3 - 5y + 16 + 4y^2 - y + 9

<u>Step 2:  Combine like terms</u>

-4y^3 - 5y + 16 + 4y^2 - y + 9

-4y^3 + 4y^2 - 6y + 25
