Answer:
180/t = r
Step-by-step explanation:
In this question, we would have to write an equation that represents the scenario given.
We know that the car traveled 180 miles at a constant rate.
We would use the y = mx + b format for the equation, but replacing the variables with "r" and "t"
We know that 180 will be our y-variable, since that would be the base of the equation:
180 = ???
And to find how long/fast it will take the car, we would need to multiply the rate of speed "r" and time "t" in order to get our distance.
Plug it into the equation:
180 = rt
With this set up, you can find the rate of speed of the car when you know the time.
You would simply solve it as:
180/t = r
The problem requires us to find the rate or speed of Lilli in miles per hour. Therefore, we just have to divide the given data.
12/110 = 0.10909.... Therefore, Lilli's speed or rate is 0.11 mi/hr.
The answer is 1.804 hope it helps
Why not write all of the numbers in decimal fraction form, to make them easier to compare?
68 2/3 = 68.666...
72 1/2 = 72.500
68 3/10 = 68.300
74 7/11 = 74.636...
68 1/2 = 68.500
550/8 = 68.750
Now ask yourself: Which of the last four numbers is between 68.666.. and 72.500?
Answer:
his speed would be 4.5 miles per hour
Step-by-step explanation:
if you do the distance divided by the hours you will get the answer.
22.5/5=4.5
