1/2(12-v)=1/6(v-6)
6-1/2v=1/6v-1
7=2/3v
v=21/2 or 10.5
Given:
Table of values.
The train travels at a constant speed.
To find:
The speed of train in miles per hour.
Solution:
From the given table consider any two points, i.e., (0.5,22.5) and (1,45).
The train travels at a constant speed. It means, there is a linear relationship between time and distance.
The average rate of change (Slope) of a linear relationship is





So, average rate of change in distance with respect to time is 45.
Therefore, the speed of the train is 45 miles per hour.
