Question

A train running at the speed of $60$ km/hr crosses a pole in $9$ seconds. What is the length of the train?

• A. $120$ m
• B. $180$ m
• C. $150$ m
• D. $220$ m

Answer 1

The correct option is C $150$ m

Speed $=(60\times \frac{5}{18})$m/sec
$=\frac{50}{3}$ m/sec
Length of the train $=(\text{Speed}\times \text{Time})$
$\therefore$ Length of the train $=(\frac{50}{3}\times 9)=150$ m
