We want to write an inequality that tells how much Hannah should walk this week. The inequality will be:
x ≥ (3 + 3/4) mi
<h3>
Finding the inequality:</h3>
We know that she already did walk 2 3/4 miles this week, and she wants to walk at least 6 1/2 miles.
So to reach that minimum, she needs to walk:
(6 1/2)mi - (2 + 3/4) mi = (3 + 3/4) mi
And she can walk that or more, so the inequality is:
x ≥ (3 + 3/4) mi
Where x represents how much she will walk this week.

You put them in fractions then cross multiple.
18/12 and 3/x so that's 36 equals 18x then you divide 36 by 18 which is 2.
The minimum and maximum number of hours the plane will travel at that speed are; at least 0.875 hours and at most 1.375 hours
<h3>How to Solve Absolute Value Inequality?</h3>
We are given that the speed of the plane is 200 miles per hour.
Now, formula for time taken is;
Time = Distance/Speed
If the speed is 225 ± 50 miles, then it means that;
Maximum distance = 275 miles
Minimum distance = 175 miles
Thus, we can say that;
Minimum number of hours = 275/200 = 1.375 hours
Maximum number of hours = 175/200 = 0.875 hours
