Answer:
10 seconds
Step-by-step explanation:
as they are moving in the opposite direction
so the distance will be the length of train which is less than the other one
so length of train a = speed * time = s * 10 =10s
length of train b = s * 15 = 15s (as speed is same)
now distance need to be travelled = 10s
time = distance/ speed
= 10s / s = 10 seconds
