Two trains travel directly toward each other. One of the trains travels at a rate of 12 km/h while the other travels at a rate o
Schach [20]
Write the equation of the first train: x = 12t
Write the equation of the second train: y = -20t+72, assuming the train one is at the origins when t = 0. 
Now solve the equation: 12t=-20t+72, 
32t = 72, then t = 2.25 hours. The two train meet after 2.25 hours. 
Now the equation of the <span>pigeon is like this: x = 48t. 
</span>Then for t = 2.25, we get
 x=2.25\times48=108 km

<span>The Hyde has flown 108 km when the trains meet.</span>

What is the length of AB when A is (-7,-6) and B is (1,0)
NemiM [27]

Answer:

The answer is

<h2>10 units</h2>

Step-by-step explanation:

The distance between two points can be found by using the formula

d =  \sqrt{( {x1 - x2})^{2}  +  ({y1 - y2})^{2} }  \\

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

A (-7,-6) and B (1,0)

The distance between them is

|AB|  =  \sqrt{( { - 7 - 1})^{2}  +  ({ - 6 - 0})^{2} }  \\  =  \sqrt{ ({ - 8})^{2}  +  ({ - 6})^{2} }   \\  =  \sqrt{64 + 36}  \\  =  \sqrt{100}  \:  \:  \:  \:  \:  \:  \:  \:

We have the final answer as

<h3>10 units</h3>

Hope this helps you
