Answer:

1) if they are moving away from each other it will take 1.43 secs

2) if they are moving towards each other then it will take 1.11 secs

Explanation:

Distance between them is 10 m

Speed  ( if they are moving towards each other)= distance/time

time = 10/8+1

time = distance / speed= 10/9=  1.11 secs

if they are moving away from each other than it will take

time = 10/8-1= 10/7= 1.43 secs
