Excluding the Stoppages i.e. Non-stop, the speed of a Bullet train is ...
To solve this problem, we can use the concept of average speed.
Let's assume the total distance traveled by the train is D km.
We know that the speed of the train excluding stoppages is 540 kmph and including stoppages is 450 kmph.
Average speed is defined as the total distance traveled divided by the total time taken.
So, we can write the equation as:
D / Total time = Average speed
The total time can be divided into two parts: the time taken for the non-stop journey and the time taken for the stoppages.
Let's assume the time taken for the non-stop journey is T1 hours and the time taken for the stoppages is T2 hours.
So, the equation becomes:
D / (T1 + T2) = Average speed
We can rearrange this equation to solve for T2:
T2 = (D / Average speed) - T1
Since we have the speeds in kmph, we need to convert the speeds to km/min in order to calculate the time in minutes.
Given that the speed of the train excluding stoppages is 540 kmph, we can convert this to km/min by dividing it by 60:
Speed excluding stoppages = 540 kmph = 9 km/min
Similarly, the speed of the train including stoppages is 450 kmph, which can be converted to km/min:
Speed including stoppages = 450 kmph = 7.5 km/min
Let's plug in these values into the equation:
T2 = (D / 7.5) - T1
Since we know that the average speed of the train is always less than the speed excluding stoppages, we can say that the time taken for the non-stop journey (T1) is 0. Therefore, the equation simplifies to:
T2 = D / 7.5
Now, we need to find the value of T2 in minutes. To do that, we multiply T2 by 60:
T2 (in minutes) = (D / 7.5) * 60
Since we are given the answer in minutes, we need to find the value of D that satisfies the condition. The only option that satisfies the condition is 10 minutes (option A).
Therefore, the correct answer is option A) 10 minutes.
Let's assume the total distance traveled by the train is D km.
We know that the speed of the train excluding stoppages is 540 kmph and including stoppages is 450 kmph.
Average speed is defined as the total distance traveled divided by the total time taken.
So, we can write the equation as:
D / Total time = Average speed
The total time can be divided into two parts: the time taken for the non-stop journey and the time taken for the stoppages.
Let's assume the time taken for the non-stop journey is T1 hours and the time taken for the stoppages is T2 hours.
So, the equation becomes:
D / (T1 + T2) = Average speed
We can rearrange this equation to solve for T2:
T2 = (D / Average speed) - T1
Since we have the speeds in kmph, we need to convert the speeds to km/min in order to calculate the time in minutes.
Given that the speed of the train excluding stoppages is 540 kmph, we can convert this to km/min by dividing it by 60:
Speed excluding stoppages = 540 kmph = 9 km/min
Similarly, the speed of the train including stoppages is 450 kmph, which can be converted to km/min:
Speed including stoppages = 450 kmph = 7.5 km/min
Let's plug in these values into the equation:
T2 = (D / 7.5) - T1
Since we know that the average speed of the train is always less than the speed excluding stoppages, we can say that the time taken for the non-stop journey (T1) is 0. Therefore, the equation simplifies to:
T2 = D / 7.5
Now, we need to find the value of T2 in minutes. To do that, we multiply T2 by 60:
T2 (in minutes) = (D / 7.5) * 60
Since we are given the answer in minutes, we need to find the value of D that satisfies the condition. The only option that satisfies the condition is 10 minutes (option A).
Therefore, the correct answer is option A) 10 minutes.
