Question: A man sitting in a train is counting the pillars of electricity. The distance between two pillars is 60 meters and the speed of the train is 36 km/hr. In 5 hours, how many pillars will be count?

Solution:
Distance covered by the train in 5 hours = (36 × 5) km
= (180 km × 1000)
= 180000 m

∴ Number of pillars counted by man = {(180000/60) + 1}
= (3000 + 1)
= 3001

[ Since the man start counting with pillar and end with pillar so 1 is added]
