I will use 'hr' to mean hour and 'hrs' to mean hours.
<u>The airplane flies:</u>
200 miles per hr
400 miles per hr
600 miles per hr
Average speed = Total distance ÷ total time
= (200 + 400 + 600)miles ÷ 3hrs = 400miles/hr
Time = Distance ÷ Average speed
= 2000miles ÷ 400miles/hr = 5hrs
We are required to write an inequality for the expression and also solve it
The number y is at least 10.9
let
the unknown number = y
The sum of a number y and 6.2 = y + 6.2
y + 6.2 ≤ -4.7
y ≤ -4.7 - 6.2
y ≤ 10.9
Therefore,
The expression is represented by the inequality y + 6.2 ≤ -4.7 and y ≤ 10.9

Answer:
Sheila earned $120 in interest.
Step-by-step explanation:
In order to calculate the interest earned by Sheila we can use the simple interest formula shown bellow:
i = P*r*t
Where i is the interested earned, P is the amount invested, r is the interest rate and t is the total time. For this case we have:
i = 800*0.03*5
i = 24*5
i = 120
Sheila earned $120 in interest.
