Question

Train P and Q have lengths of 400 m and 600 m respectively .They are running on parallel tracks towards each other .Find the total distance covered by the two trains from the time they start to cross each other to the time they completely cross each other.​

Answer 1

the total distance covered by the two trains P & Q to Cross each other = 1 km  when Train P and Q have lengths of 400 m and 600 m respectively

Step-by-step explanation:

Train P and Q are running on parallel tracks towards each other

the total distance covered by the two trains from the time they start to cross each other to the time they completely cross each other.​

= Length of train P + Length of Train Q

Length of train P  = 400 m

Length of Train Q  = 600 m

Total Distance covered = 400 + 600 = 1000 m =  1 km

Answer 2

total distance covered = 400+600= 1000m
