Question

2. A train starts from rest and covers a distance of 450 m in 2 min. Calculate the speed of the
train in (i) m/s
[1) 3.75 m/s ​

Answer 1

Answer:

Explanation:

Given,

Distance covered = 450 m

Time taken = 2 min = 2 × 60 = 120 seconds

To Find,

Speed

Formula to be used,

Speed = Distance/Time taken

Solution,

Putting all the values, we get

Speed = Distance/Time taken

Speed = 450/120

Speed = 3.75 m/s

Hence, the speed of the train is 3.75 m/s.

Answer 2

Answer:

Question :-

• A train starts from rest and covers a distance of 450 m in 2 min. Calculate the speed of the train in m/s.

Given :-

• Calculate the speed of the train in m/s.

Find Out :-

• A train starts from rest and covers a distance of 450 m in 2 min.

Solution :-

Let's, calculate by convert time into seconds,

$\curlyeqsucc$ Time taken = 2 min

$\curlyeqsucc$ Time taken= 2 × 60

$\curlyeqsucc$ Time taken = 120 seconds

Now, calculate the speed of the train,

Given in the question :

• Time = 120 seconds
• Distance covered = 450 m

We know that,

$\red{ \boxed{\sf{Speed = \dfrac{Distance}{Time}}}}$

Substituting the values, we get,

$\implies$ Speed = $\cancel{\dfrac{450}{120}}$

$\implies$ Speed = $\dfrac{45}{12}$

$\implies$ Speed = 3.75 m/s

Therefore, the speed of the train is 3.75 m/s.
