Correct Answer - Option 1 :
\(\frac{3}2\)
Given:
One travels north at 60 Kmph and the other travels south at 40 Kmph.
Formula used:
Time = Distance/Speed
Calculation:
Trains running opposite direction,
Then both train speed must be add
Total speed = (60 + 40) kmph
Distance = 150 km
According to the question,
Time = 150/100
⇒ T = 3/2
∴ 3/2 hours will the train be 150 km apart.
