A train running at the speed of 60 km/hr crosses a pole in 9 seconds. What is the length of the train?
120 metres
180 metres
324 metres
150 metres
Explanation:
| Speed=$ \left(60 \times\dfrac{5}{18} \right) $m/sec=$ \left(\dfrac{50}{3} \right) $m/sec. |
| Length of the train = $(Speed \times Time) = \left(\dfrac{50}{3} \times 9\right) $m = 150 m. |
