Answer:
Explanation:
Distance and time are directly related, meaning that distance / time = constant.
In this case the constant is the rate or speed.
Thus you can write:
And, given that covering 30 miles requires 25 minutes, to calculate the time needed to cover 25 miles, you can set this proportion:
- 30 miles / 25 min = 25 miles / t
To clear t you do cross multiplication:
- t × 30 miles = 25 miles × 25 min
Divide both sides by 30 miles:
- t = 25 miles × 25 min / 30 miles = 20.8 min ≈ 21 min ← answer

Answer:
The system has no solution.
Step-by-step explanation:
In order for the system to have a solution, both graphs must have an intercept to each others. We see in the picture that both graphs are parallel and do not have any interceptions which we don't know the solution to the system.
That means if graphs are parallel and have no interceptions, there are no solutions. The system of equations are for finding the interceptions of both graphs. But of course! Parallel lines do not intercept.
