Select the correct answerA train covers a certain distance in 210 minutes at a speed of 60 kmph. The time taken by the train, to cover the same distance at a speed of 80 kmph is?

Sure, let's solve this step by step:

1. First, we need to find the distance covered by the train. We know that distance = speed * time. The speed of the train is 60 kmph and the time is 210 minutes, which is 3.5 hours (since 1 hour = 60 minutes). So, the distance covered is 60 kmph * 3.5 hours = 210 km.

2. Now, we need to find the time taken by the train to cover the same distance at a speed of 80 kmph. We know that time = distance / speed. So, the time taken is 210 km / 80 kmph = 2.625 hours.

3. To convert this time into minutes, we multiply by 60 (since 1 hour = 60 minutes). So, the time taken is 2.625 hours * 60 = 157.5 minutes.

So, the train would take 157.5 minutes to cover the same distance at a speed of 80 kmph.

Sure, let's solve this step by step:

1. First, we need to find the distance covered by the train. We know that distance = speed * time. The speed of the train is 60 kmph and the time is 210 minutes, which we need to convert to hours because the speed is in km/h. So, time = 210/60 = 3.5 hours.

2. Therefore, the distance covered by the train = 60 kmph * 3.5 hours = 210 km.

3. Now, we need to find the time taken by the train to cover the same distance at a speed of 80 kmph. We know that time = distance/speed.

4. So, the time taken = 210 km / 80 kmph = 2.625 hours.

5. To convert this back to minutes, we multiply by 60. So, the time taken = 2.625 hours * 60 = 157.5 minutes.

Therefore, the train would take 157.5 minutes to cover the same distance at a speed of 80 kmph.
