Question

two trains starting from two points P and Q respectively and travel towards each other at a speed of 50 km per hour and 40 km per hour respectively find the time in which they meet each other. If the distance between them is 100 kilometre​

Answer 1

Answer:

100+50+40 =190 km is correct answer

Answer 2

It takes 1.11 hour to meet each other.

Step-by-step explanation:

Since we have given that

Speed of first train = 50 km/hr

Speed of second train = 40 km/hr

They are travelling towards each other,

So, Relative speed = $50+40=90\ km/hr$

Distance between them = 100 km

So, Time is given by

$\dfrac{Distance}{speed}\\\\=\dfrac{100}{90}\\\\=1.11\ hour$

Hence, it takes 1.11 hour to meet each other.
