Question

If a train with a speed of $60$ km/hr crosses a pole in $30$ seconds, what is the length of the train in metres ?

• A. $500$ m
• B. $1800$ m
• C. $200$ m
• D. $900$ m

Answer 1

The correct option is A $500$ m

Speed of train $=60$ km/hr $=(60\times \frac{5}{18})$ m/s $=\frac{50}{3}$ m/s
Time taken $=30$ seconds
Therefore, length of train is $(\frac{50}{3}\times 30)$ m $=500$ m
