Given:
Table of values.
The train travels at a constant speed.
To find:
The speed of train in miles per hour.
Solution:
From the given table consider any two points, i.e., (0.5,22.5) and (1,45).
The train travels at a constant speed. It means, there is a linear relationship between time and distance.
The average rate of change (Slope) of a linear relationship is
So, average rate of change in distance with respect to time is 45.
Therefore, the speed of the train is 45 miles per hour.
Answer:
I think its the second one but I might not be right.
Step-by-step explanation:
So, a full circle has 360°, thus when the minute hand does one hour, it does a full circle, therefore 360°.
now, how many degrees are there in 1 minute? well, there are 60 minutes in 360°, therefore there are 360/60 degrees in 1 minute, or 6°.
now, we know in 1 hour there are 360°, how many in 27 minutes? well, 27 * 6, or 162°. So after 1hr and 27min, the minute hand has done 360+162 or 522°.
we also know the minute hand is 2 inches long, thus
which is roughly 18 inches rounded up.
Answer:
You can display data in a histogram by labeling the x and y axis with your numbers provided. Then you put in the amount of numbers.
