The distance between two trains is 150km having one train speed 60km/h and other is 40km/h. What will be time they can meet in hour? 1

Answer: 1 hour 30 minutes
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:

60km/h+40km/h=100km/h60 , 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:

Time=DistanceRelative Speedtext{Time} = frac{text{Distance}}{text{Relative Speed}} Time=150km100km/h=1.5hours=1hour30minutestext{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
