Question

A train covers a distance of 540Km in 3 hours?Calculate its speed both in km/h and m/s.

Answer 1

km/hrs=108km/hrs

m/s=50m/s

Step-by-step explanation:

speed=dis/time

(in km/hr)

speed=540/3

          =180km/hr

(in m/sec)

1hr=3600sec

3hrs=10800

1km=1000m

540km=540000m

= 540000/10800

  =50m/sec

hope you got your answer...

Answer 2

Given:

A train covers a distance of 540Km in 3 hours

To Find:

Calculate its speed both in km/h and m/s.

Solution:

Speed is the measure of how fast an object is moving with respect to time.

The SI unit of speed is m/s but it can also be expressed in various other units. To convert a unit from km/hr to m/s we multiply the unit with km/hr with 5/18.

The formula for speed is,

$Speed=\frac{distance}{time}$

Now put the values given in the question to find the value of speed,

[tex]Speed=\frac{540}{3 } \\ =180km/hr[/tex]

Now the speed is 180km/hr, which when converted to m/s will be,

[tex]Speed=180km/hr*\frac{5}{18} \\ =50m/s[/tex]

Hence, the speed of the train in km/hr is 180 and in m/s is 50.
