Answer:
On the way out the train traveled at about 40 mph, while on the return it did so at 20 mph.
Step-by-step explanation:
Since an empty freight train traveled 60 miles from an auto assembly plant to an oil refinery, and there, its tank cars were filled with petroleum products, and it returned on the same route to the plant, and the total travel time for the train was 4.5 hours, if the train traveled 20 mph slower with the tank cars full, to determine how fast did the train travel in each direction the following calculation must be performed:
60/20 = 3
60/40 = 1.5
60/20 = 3
3 + 1.5 = 4.5
Therefore, on the way out the train traveled at about 40 mph, while on the return it did so at 20 mph.
The question is incomplete:
Two ovens have measurements as shown. Which oven has a greater volume? How much greater is its volume?
The image with the information is below.
Answer:
-Oven B has a greater volume.
-Its volume is greater by 768 in³.
Step-by-step explanation:
First, you have to calculate the volume of each oven by multiplying the area of the base by the height:
Oven A: 576 in²*15 in= 8640 in³
Oven B: 672 in²*14 in= 9408 in³
Now, you have to calculate the difference between the volumes:
9408-8640=768
According to this, the answer is that oven B has a greater volume. Its volume is greater by 768 in³.
Note that perimeter of rectangle
So we have to solve for width or w.
Width of a rectangle is 5 units.
Hope this helps.
