Step-by-step explanation:

Speed of train = 45 km/hr

1 km = 1000 m

1 hour = 3600 seconds

So, Speed of train in m/s =

$45 \times \frac{1000}{3600}=12.5m/s$

Length of train = 125 m

Length of platform = 625 m

Total length = 625+125=750 m

Time taken to pass a platform 625 m long =

$\frac{Distance}{Speed}=\frac{750}{12.5}=60 seconds$

So, it will take 60 seconds to pass a platform 625m long
