To find when the temperatures at Kent and Row will be the same, we can set the equations for the temperatures at each location equal to each other:
-7 + 2.5t = 19 - 4t
Now, let's solve this equation for t:
-7 + 2.5t = 19 - 4t
Combining like terms, we get:
6.5t = 26
Dividing both sides by 6.5, we find:
t = 4
Therefore, it will take 4 hours for the temperatures at Kent and Row to be the same.
To determine the final temperature when they are the same, we can substitute t=4 back into either equation. Let's use the equation for the temperature at Kent:
temperature at Kent = -7 + 2.5t
temperature at Kent = -7 + 2.5(4)
temperature at Kent = -7 + 10
temperature at Kent = 3
So, when the temperatures at Kent and Row are the same, the temperature will be 3 degrees.
the temperature at Kent is -7 degrees and increasing at 2.5 degrees per hour. The temperatire at row is 19 degrees decreasing at 4 degrees per hour. When will they be the same? and what temperatore?
let t = hours running time.
-7+2.5t = temperature at Kent at time t.
19-4.0t = temperature at row at time t.
Set them equal to each other and solve for t which will be the number of hours for the two temperatures to be the same.
Then use t and either equation to determine the final temperature.
