Question

two trains 110 metre and 100 metre long are running on parallel track in the same direction with a speed of 46 km per hours and 39 km per hour respectively how long will it take them to be clear of each other​

Answer 1

Answer:

108sec

Step-by-step explanation:

average distance= (110+100)m = 210m

relative velocity of the trains= (46-39)km/hr {since they are in same direction} = (7*1000/60*60)m/sec

time taken=distance/velocity= (210*60*60)/(7*1000) = 108 sec
