Flauer [41]

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.

For the given <span>quadratic function ⇒⇒ A(t) = −(t − 11)² + 115</span>
From the attached figure which represents the graph of the given function
the maximum will be at point (11,115)

So, <span>the highest altitude (in meters) = 115 meter
