The length of the goods train is 270 meters.

Given that, a goods train runs at the speed of 72 kmph and crosses a 250 m long platform in 26 seconds.

<h3>What is the distance formula with speed and time?</h3>

Speed is defined as the rate at which an object moves from one place to another in a given interval of time. It is a scalar quantity as it defines only the magnitude not the directions of an object moving. The S.I. unit of speed is m/s.

The speed of a moving object can be calculated as Speed = Distance / Time.

Now, to convert km/h to m/sec multiply the measure by 5/18.

That is, 72 × 5/18 = 20 m/sec

Let the length of the train be x metres.

So, then (x+250) / 26 = 20

⇒x+250=520

⇒x=270 meters

Therefore, the length of the goods train is 270 meters.

Rewrite the polynomial in the form ax^2+bx+c and then identify the values of a, b, and c
Anestetic [448]
10x - x^2 + 1
first make both sides equal to 0

10x - x^2 + 1 = 0
get rid of x^2 by adding it to both sides

10x + 1 = x^2
get rid of 10x and +1 by subtracting both sides by the values

0 = x^2 - 10x - 1

Now you get x^2 - 10x - 1

a= 1 b= -10 c= -1

Matrix A has order 4 x 8, Matrix B has order 4 x 16.
Scorpion4ik [409]
Matrix A order is 4x8.
Matrix B order is 4x16.
AB cannot result because an (m x n) can only be multiplied by an (n x p) matrix and orders don't match the requirements.
BA has the same negative result.
