Person a can walk 5 miles in an hour.
Person b can walk 3 miles in an hour.
They are 12 miles apart, and after an hour they have covered 8 miles.
8:1 = 12:x
8x = 12
x = 1.5
After an hour and a half, they will meet.
Check:
5 miles : 1 hour = 7.5 miles : 1.5 hours
3 miles : 1 hour = 4.5 miles : 1.5 hours
Together, they should have covered 12 miles.
7.5 + 4.5 = 12
It takes 1.5 hours to meet eachother.

Answer:
A(9) = -52
Step-by-step explanation:
The given sequence is :
A(n)=-4 -6(n-1)
We need to find the 9th term of the above sequence.
To find it, put n = 9 in the above sequence.
A(9) = -4 -6(9-1)
= -4-6(8)
= -4-48
= -52
Hence, the 9th term of the sequence is -52.
