For this case, the first thing that we must take into account is the following conversion:
1 hr = 60 min
The time of the first race in minutes is:
1 hour 10 minutes = 60 minutes + 10 minutes
1 hour 10 minutes = 70 minutes
Now we define one variable:
x: time remaining to beat the previous time
The inequation that models the problem is:
Answer:
An inequality that can be used to find how much longer she can run and still beat her previous time is:
1 hr = 60 min
The time of the first race in minutes is:
1 hour 10 minutes = 60 minutes + 10 minutes
1 hour 10 minutes = 70 minutes
Now we define one variable:

Step-by-step explanation:
Let the first angle be degrees
Let the second angle be degrees
Let the third angle be degrees
It is given that sum of angles is degrees.
so, ...(i)
It is given that sum of the measures of the second and third angles is two times the measure of the first angle.
...(ii)
It is given that the third angle is 26 more than the second.
...(iii)
using (ii) and (iii),
