Answer:
The answer to your question is SV = 32
Step-by-step explanation:
Data
T = mid point
ST = x + 4
TV = 2x - 8
SV = ?
Process
1.- If T is the mid point of SV, that means that the distance from ST to SV is the same.
ST = TV
2.- Substitution
x + 4 = 2x - 8
-Solve for x
x - 2x = -8 - 4
-Simplifying
-x = -12
-Result
x = 12
3.- Find the length of SV
SV = ST + TV
SV = x + 4 + 2x - 8
SV = 12 + 4 + 2(12) - 8
SV = 16 + 24 - 8
SV = 40 - 8
SV = 32
Answer:
The second train speed is 356.4 miles per hour
And, the first train speed is 361 miles per hour
Step-by-step explanation:
The computation of the speed of each train is as follows
Given that
The Sum of the speed of two trains is 717.4 miles per hour
Let us suppose the second train speed be x
So for the first train, the speed is x + 4.6
Now the equation is
x + x + 4.6 = 717.4
2x + 4.6 = 717.4
2x = 717.4 - 4.6
2x = 712.8
x= 356.4
Therefore the second train speed is 356.4 miles per hour
And, the first train speed is = 356.4 + 4.6 = 361 miles per hour
