Solution

To solve this problem, we need to use the formula for distance covered under constant acceleration, which is d = ½ a t².

Here, a is the acceleration and t is the time. The problem provides us with a = 0.5 m/s² and t = 1 minute. However, we need to convert the time from minutes to seconds because the acceleration is given in metres per second per second.

1 minute = 60 seconds

Now we can substitute a and t into the formula:

d = ½ * 0.5 m/s² * (60 s)² d = 0.25 m/s² * 3600 s² d = 900 metres

So, the train will have covered 900 metres in 1 minute.
