Answer:
The speed of the bus is 74.242 kilometers per hour.
Step-by-step explanation:
Let suppose that bus runs at constant speed and that speed is measured in kilometers per hour. Then, the speed of the bus (
), in kiometers per hour, is determined by following kinematic expression:
(1)
Where:
- Travelled distance, in kilometers.
- Time, in hours.
If we know that
and
, then the speed of the bus is:
![v = \frac{s}{t}](https://tex.z-dn.net/?f=v%20%3D%20%5Cfrac%7Bs%7D%7Bt%7D)
![v = 74.242\,\frac{km}{h}](https://tex.z-dn.net/?f=v%20%3D%2074.242%5C%2C%5Cfrac%7Bkm%7D%7Bh%7D)
The speed of the bus is 74.242 kilometers per hour.

Answer:
Step-by-step explanation:
(-2 + x)/2= 4
-2 + x = 8
x = 10
(2 + y)/2 = -3
2 + y = -6
y = -8
(10, -8) for endpoint H
