Explanation

When two objects are moving towards each other, their relative speed is the sum of their individual speeds.

• Speed of the first train = 60 km/h
• Speed of the second train = 40 km/h
• Distance between them = 150 km

The relative speed is:

$$60 , text{km/h} + 40 , text{km/h} = 100 , text{km/h}$$

Now, to find the time it takes for the trains to meet, use the formula:

$$text{Time} = frac{text{Distance}}{text{Relative Speed}}$$ $$$$Time=150 km100 km/h=1.5 hours=1 hour 30 minutestext{Time} = frac{150 , text{km}}{100 , text{km/h}} = 1.5 , text{hours} = 1 , text{hour} , 30 , text{minutes}Time=150km/100km​/h=1.5hours=1hour30minutes
