Question

what is the average speed of the train when the total distance covered is 50km and total time taken is 1hour 30 minutes​

Answer 1

Answer:-

Av = 33.3 km/h

Given :-

S = 50 km

Total time taken = 1 hr 30 m

To find :-

Average speed

Solution:-

Average speed :- It is the ratio of the total distance covered by total time taken by the body is known as average speed.

From definition,

★$\boxed{\sf{A_v = \dfrac{Total distance covered}{Total time taken}}}$

→$T = 1+\dfrac {1}{2 }$

→$T = \dfrac{2 +1}{2}$

→$T = \dfrac{3}{2}h$

Now,

put the given value,

→$A_v = \dfrac{50}{\dfrac{3}{2}}$

→$A_v = \dfrac{100}{3}$

→$A_v = 33.3 km/h$

hence, average speed of train will be 33.3km/h.

Answer 2

Answer:

Average Speed is 33.3 km/h

Explanation:

Given Problem:

What is the average speed of the train when the total distance covered is 50km and total time taken is 1hour 30 minutes.

Solution:​

To Find:

Average speed.

-----------------------

Method:

Given that,

Speed = 50 km.

Total time taken = 1 hour 30 minutes.

We know that,

★$A_v = \dfrac{Total\: distance\: coevered}{Total\: time\: taken}$★

$Now, Convert\: time\: into\: hours$

$T = 1+\dfrac{1}{2}$

$T = \dfrac{2+1}{2}$

$T = \dfrac{3}{2}h$

Now,

Putting values in equation,

$A_v = \dfrac{50}{3}$

$A_v = \dfrac{100}{3}$

$A_v = 33.3 km/h$

Hence,

It implies that the average speed of train will be 33.3km/h.
