Question
Chapter 5.8, Problem 21P
To determine
To find how far apart two cities .
Expert Solution & Answer
Answer to Problem 21P
The distance between two cities is 160 km.
Explanation of Solution
Formula:
Given that the rail line between two cities consists of two segments, one 96 km longer than the other.
Now, A passenger train average
Formula:
Let the shorter segment of rail be x then the longer segment is
Therefore, the total length of the rail line is
First, to determine the time of the shorter segment where distance is x and speed
similarly to determine the time of the longer segment where distance is x+96 and speed
Now, the total time
Thus , the total time is equal to the time of shorter segment with the longer segment time
Now, Add equation ( i ) and equation ( ii ) and compare with equation ( iii)
Simplify the equation
Hence, the total distance between the two cities is total distance
