Answer:
117mph
Step-by-step explanation:
Given that
Total number of stations= 3
Total average time of journey of train = 65
total stop time at three stations = 3×2 =6 min
Total distance between stops = 115 miles
as we can see
Total time train was travelling = 65- 6 =59 min
so, average speed of train can be calculated as:
Average Speed = 
Average Speed = 
To convert this speed into miles per hour (mph) multiply the above speed by 60
Average speed = 60×1.95 =117 mph
So the average speed of train is 117mph.
If you alter the "c" value, then you are <u>moving the graph up</u> <em>(or down if c is negative)</em>.
Since you are shifting the graph up, the y-intercept ("h" in your graph) will move up.
Since you are shifting the graph up, then the maximum will shift up.
Since you are shifting the graph up, then the x-intercept ("t" in your graph) will increase (move to the right).
Answer: K
Answer:
10
Step-by-step explanation:
isolate y by adding 5 to each side. Now you have y=x+10. 10 is the c value, which is the y-intercept
