A train covers a distance in 5 hours at 45 km/h. What speed is required to cover the same distance in 3 hours?

A train covers a distance in 5 hours at 45 km/h. What speed is required to cover the same distance in 3 hours?

ایک ٹرین 45 کلومیٹر فی گھنٹہ کی رفتار سے 5 گھنٹے میں فاصلہ طے کرتی ہے۔ اسی فاصلے کو 3 گھنٹے میں طے کرنے کے لیے کس رفتار کی ضرورت ہے؟
Explanation

To find the required speed, we first calculate the distance covered by the train:

Distance=Speed×Time=45km/h×5hours=225kmtext{Distance} = text{Speed} times text{Time} = 45 , text{km/h} times 5 , text{hours} = 225 , text{km}

Now, to cover this 225 km in 3 hours, the required speed is:

Speed=Distance/Time=225km/3hours=75km/h
