Here are the rates of the trains:
(n represents train A's speed)
A: n
B: n + 10
We know it is 5 hours, and total distance, so:
5(n) + 5(n + 10) = 1250
5n + 5n + 50 = 1250
10n = 1200
Divide:
n = 120
One train goes 120, the other goes 130
<u>ANSWER: </u>
The algebraic expression for one-eight of the sum of a number and three is 
<u>SOLUTION:
</u>
Given, "x" represent the unknown value.
We have to write the algebraic expression for:Here, the number is unknown term, so x represents the number.
Now according to given information ,
One - eight of the sum of a number and three.
→ 
of the sum of x and 3
→ 
→ 
→
Hence the algebraic expression for one-eight of the sum of a number and three is
A = 1/5
d = T2-T1
d = 1/10 - 1/5
d = 1/10 - 2/10
d = - 1/10
T4 = 1/5 + 3(-1/10)
= 1/5 - 3/10
= 2/10 - 3/10
= - 1/10
