Question

Поезд со скоростью 36км в час проходит мимо идущего навстречу пешехода со скоростью 4км в час за54 секунды найти длину поезда

Answer 1

36-4=32км/ч
l= (32*54)/3600=0,48 км =480 метров

Answer 2

Calculating the Length of the Train

To find the length of the train, we can use the formula: Length = (Relative Speed * Time Taken) / (Speed of Train - Speed of Pedestrian)

Given: - Speed of the train (relative speed): 36 km/h - Speed of the pedestrian: 4 km/h - Time taken: 54 seconds

Using the formula: Length = (36 + 4) * (54 / 3600) / (36 - 4)

Calculating: Length = (40) * (0.015) / 32 Length = 0.6 / 32 Length = 0.01875 km

Answer

The length of the train is 0.01875 kilometers.
