320yd2/ 4yd = 80yd
The length should always be longer unless it is a square.
Given the distance travelled and the time elapsed, the average speed of the train is approximately 1.63 miles per minutes.
<h3>What is the average speed of the train?</h3>
Given that;
- Distance traveled d = 75miles
- Time elapsed t = 46 min
- Average speed s = ?
Average speed = distance traveled / elapsed time
Average speed = 75miles / 46min
Average speed = 1.63 miles per minutes
Given the distance travelled and the time elapsed, the average speed of the train is approximately 1.63 miles per minutes.

To solve this problem you must apply the proccedure shown below:
1. You have that :
-The <span>estimate from the moving is $675 for 6 hours of packing and 5 hours of moving.
- </span>The cost will decrease to $425 for 4 hours of packing and 3 hours of moving.<span>
x: rate for packing.
y: rate for moving.
6x+5y=675
4x+3y=425
2. When you solve the system of equations shown above, you obtain:
x=50
y=75
Therefore, the answer is: $50 (Rate for packing) and $75 (Rate for moving).

Answer:
8x + 60
Step-by-step explanation:
4(x + 5) + 2(x - 10) + 2(x + 30)
= 4x + 20 + 2x - 20 + 2x + 60 (combine like terms)
= 8x + 60
