Answer:
<u>The semi-trailer truck has the fastest average speed</u>
Step-by-step explanation:
Let's recall that the formula of the average speed is:
Average speed = Distance/Speed
Now, we can calculate the average speed for each class of vehicle, as follows:
Flatbed truck average speed = 144/5 = 28.8 miles per hour
<u>Semi-trailer truck average speed = 327/4 = 81.75 miles per hour</u>
Tanker truck average speed = 589/15 = 39.27 miles per hour
Which truck has the fastest average speed?
<u>The semi-trailer truck has the fastest average speed</u>
I don’t know I hope u get it
Hey, this is not a complete question, there is not visible graph. You may wanna retry to set up your question and make sure the graph is there
Your final answer is going to be 4r + 3r ^2 +7
Answer:
The linear speed in which Darlene is traveling is 24.74 miles per hour.
Step-by-step explanation:
The wheel experiments rolling, which is a combination of translation and rotation. The point where linear speed happens is located at geometrical center of the wheel and instantaneous center of rotation is located at the point of contact between wheel and ground. The linear speed (
), measured in inches per second, is defined by following expression:
(1)
Where:
- Radius of the wheel, measured in inches.
- Angular speed, measured in radians per second.
If we know that 
and 
, then the linear speed, measured in miles per hour, in which Darlene is traveling is:
The linear speed in which Darlene is traveling is 24.74 miles per hour.
