Answer:
Given distance=360 km.
Let the speed of the train be x km/hr.
Speed when increased by 5 km/hr =(x+5) km/hr

+45x−40x−1800=0
x(x+45)−40(x+45)=0
(x−40)(x+45)=0
x=40,−45
The speed of the train is 40 km/hr.

Answer:
<h2>The distance between points A and B is 8.5 units, approximately.</h2>Step-by-step explanation:
In the image attached you can observe a representation of the problem.
We have to find the distance between points A and B, which have coordinates (6,0) and (0,6), respectively.
The definition of distance between to given points is
Using points A and B, the distance between is
Therefore, the distance between points A and B is 8.5 units, approximately.
