A man sitting in a train counts the electricity pillars as the train moves. The distance between two consecutive pillars is 60 meters, and the train travels at a speed of 42 km/h. Calculate the total number of pillars counted by the man in 5 hours.

Question

Accepted Answer

The speed of the train is given as 42 km/h, which can be converted into meters per hour by multiplying by 1000:  
$$
	ext{Speed in meters per hour} = 42 	imes 1000 = 42000 \, 	ext{m/h}.
$$

The train travels for 5 hours, so the total distance covered by the train is:  
$$
	ext{Total distance} = 	ext{Speed} 	imes 	ext{Time} = 42000 	imes 5 = 210000 \, 	ext{m}.
$$

The distance between two consecutive pillars is given as 60 meters. To find the number of pillars counted, divide the total distance by the distance between two pillars and add one (to include the first pillar):  
$$
	ext{Number of pillars} = \frac{	ext{Total distance}}{	ext{Distance between pillars}} + 1 = \frac{210000}{60} + 1.
$$

Simplifying:  
$$
\frac{210000}{60} = 3500.
$$  
Adding one gives:  
$$
3500 + 1 = 3501.
$$

Thus, the man counts **3501 pillars** during the journey.
