Explanation

A train speed is 27\large\frac{1}{2} or \large\frac{55}{2} km/hour.
So,
1 hour a train can cover distance \large\frac{55}{2} km
\therefore 12 hours the train can cover =\left(12\times\large\frac{55}{2}\right) km
\rightarrow 330 km.
Ans: The distance traveled by a train moving at a speed of 27 ½ km per hour for 12 hours is 330 km.

Other versions of this specific math question are:

1. How many kilometers does a train cover in 12 hours if it moves at a speed of 27 ½ km/hour consistently?
2. Calculate the total distance covered by a train moving at a speed of 27 ½ km/hour in 12 hours.
3. Find out how far a train travels when it maintains a speed of 27 ½ km/hour for a period of 12 hours.
4. Determine the distance traveled by a train traveling at a constant speed of 27 ½ km/hour for a duration of 12 hours.
