Question

The train ‘A’ travelled a distance of 120 km in 3 hours whereas another train ‘B’

travelled a distance of 180 km in 4 hours. Which train travelled faster?​

Answer 1

Answer:

In order to solve this problem k, we have to calculate the speeds of both the trains separately. <br> The train having higher speed will have travelled faster. <br> (i) We know that :

Speed =

<br> Now,

Distance travelled by train A = 120 km <br> And,

Time taken by train A = 3 h <br> So,

Speed of train A =

<br>

= 40 km/h

..(1) <br> Thus, the speed of train A is 40 kilometres per hour. <br> (ii) Again,

<br> Now,

Distance travelled by train B = 180 km <br> And,

Time taken by train B = 4 h <br> So,

Speed of train B =

<br>

= 45 km/h

...(2) <br> Thus, the speed of train B is 45 kilometres per hour. <br> From the above calculations we find that the train A travels a distance of 40 kilometres in one hour <br> whereas the train B travels a distance of 45 kilometres in one hour. Since the speed of train B is higher, therefore, train B has travelled faster.

Answer 2

$\purple \rightarrow \mathfrak \red{Question}$

The train ‘A’ travelled a distance of 120 km in 3 hours whereas another train ‘B’

travelled a distance of 180 km in 4 hours. Which train travelled faster?

$\purple \rightarrow \mathfrak \red{Answer}$

For finding the solution we need to used the formula for speed.

$\blue{speed = \frac{distance}{time}}$

So, distance covered by train A = 120 km

Time taken = 3 hours

$\blue{speed = \frac{120}{3} }$

= 40 km/hr

Now, The distance covered by train B = 180 km

Time taken = 4 hrs

$\green{speed = \frac{180}{4}}$

= 45 km/hr

So by comparing both of them we get,

45 km/hr > 40 km/hr

So train B travelled faster in comparison with train A
