Question

two trains are running towards each other at the speed of 40 km/h and 30 km/h on parallel lines . if the distance between two trains is 105 km then after how much time will they meet each other​

Answer 1

Answer:

Step-by-step explanation:

Both trains are running in oppisite direction

so effective speed=30+40=70km/hr

so time=distance/speed

=105/70 hr

=3/2 hr

=1.5 hr

Answer 2

The two trains will meet each other after 1.5 hours.

The relative speed between the two trains is equal to the sum of their individual speeds because they are approaching one another.

Their relative speed in this instance is:

40 km/h + 30 km/h = 70 km/h

This indicates that they will travel 105 km between them in total while approaching one another at a relative speed of 70 km/h.

To find the time it takes for them to meet.

We know that:

time = distance / speed

where distance is the overall distance they must travel to meet, in this case 105 km, and speed denotes their relative speed, in this case 70 km/h.

Substituting values, we get:

time = 105 km / 70 km/h = 1.5 hours

Therefore, the two trains will meet each other after 1.5 hours.
