Answer:
The variables x and y represents the input variable and y represents the output variable.
Step-by-step explanation:
Consider the provided information.
When the bivariate data are the result of two quantitative variables, it is customary to express the data mathematically as ordered pairs (
x,
y),
In mathematics or algebra x is the input variable or we can say that the independent variable.
y is the output variable or we can say that the dependent variable.
Therefore, the variables x and y represents the input variable and y represents the output variable.
SOLUTION
At the same time t,
Train 1 would have covered a distance of 80t, since distance = average speed x time.
Train 2 would have covered a distance of 70t.
Now both added should give 210 miles
That is 80t + 70t = 210
150t = 210
t = 210/150
t = 1.4 hours
