60 min = 1 hour
1st we need to know how many times 20 goes in 60 so we will divide.
60 ÷ 20 = 3
Now we will multiply to find the trains speed in miles per hour.
3 × 25 = 75
SO, the train travels 75 miles per hour.
Hope I helped ya!!
Answer:
The value of 
which makes the equation true.
Step-by-step explanation:
Given the equation
We have to find the value of r for which the equation must be true.
solving the equation
Multiply both sides by -11
Therefore, the value of which makes the equation true.
<u>VERIFICATION:</u>
Putting in the equation
∵
L.H.S = R.H.S
Therefore, the value of which makes the equation true.
If i were you, I would just plug these into my calculator.

Step-by-step explanation:
Answer:
2 hours: 27 miles, 3 hours: 40.5 miles, 3.5 hours: 47.25 miles
Step-by-step explanation:
1.) If a hiker hikes 9 miles in 2/3 of an hour, he will hike 4.5 (Half of 2/3 is 1/3 and half of 9 is 4.5) miles in 1/3 of an hour and 13.5 miles per hour. (1/3 times 3 gives us a whole and 4.5 times 3 is 13.5)
2.) 2 hours: 13.5 * 2 = 27 miles
3.) 3 hours: 13.5 * 3 = 40.5 miles
4.) 3.5 hours: 13.5 * 3.5 = 47.25 miles
