Question 102

A 275 metre long train crosses a platform of equal length in 33 seconds What is the speed of the train in kmph ?

Solution

The length of the train is 275 m. Hence, the length of the platform is also 275 m.
The train covers a total distance of 550 m in 33 seconds.

Hence, the speed of the train is $$\frac{550}{33} = \frac{50}{3}$$ m/s
To convert this speed into kmph, we need to multiply it by $$\frac{18}{5}$$

Hence, the speed of the train in kmph is $$\frac{50}{3}*\frac{18}{5} = 60$$ kmph
So, the correct option is option (b)
