correct answer: option 4 (solution below)
solution:
given:
a train covers a distance of 435 km
time taken by train is 2 hours 30 minutes.
concept used:
to convert the speed from km/hr into m/s
m/s = (5/18) × km/hr
formula used:
speed = distance/time
calculations:
we can write 2 hours 30 minutes as 2.5 hours
according to the question, we have
speed = distance/time
⇒ speed = 435/2.5
⇒ speed = 174 km/hr
to convert into m/s, multiply it by 5/18
⇒ speed = 174 × (5/18)
⇒ speed = 48.33 m/s
∴ the speed of train is 48.33 m/s.
