Question

Two trains are running in opposite direction with the same speed. If the length of each

train is 80 metres and they cross each other in 16 seconds, then what is the speed (in km/hr) of

each train?​

Answer 1

Answer:

Let the speed of each train be x m/sec.

Relative speed of the train =2x m/sec.

Step-by-step explanation:

So 2x=

12

120+120

⇒2x= 12/240

x= 2/20

=10

Speed of each train =(10×5/18)

km/hr =36 km/hr.
