Answer» Correct Answer - Option 3 : 45 Given Length of train = 150 m Time taken to cross the pole = 12 sec Formula used Distance = speed × time \(x \ m/sec = x \times {18 \over 5} km/hr\) Calculation Speed of train = distance/time ⇒ 150/12 = 25/2 m/sec \(⇒ {25 \over 2} \ m/sec = {25 \over 2} \times {18 \over 5} km/hr\) ⇒ 45 km/hr |
