Mario's unit rate is given by 900 miles/hour.
Explanation:
We have been given that Mario walked at a rate of 2/3 miles every 10 minutes.
We have the relation between speed, time and distance, which is given by
We have,
Distance = 
Time = 10 minutes
On substituting these values in the above formula, we get
![\text{Speed} = \frac{2/3}{10}\\\\ \text{Speed} =\frac{2}{10\cdot 3}\\\\ \text{Speed} =[tex]\frac{1}{15}](https://tex.z-dn.net/?f=%5Ctext%7BSpeed%7D%20%3D%20%5Cfrac%7B2%2F3%7D%7B10%7D%5C%5C%5C%5C%20%5Ctext%7BSpeed%7D%20%3D%5Cfrac%7B2%7D%7B10%5Ccdot%203%7D%5C%5C%5C%5C%20%5Ctext%7BSpeed%7D%20%3D%5Btex%5D%5Cfrac%7B1%7D%7B15%7D)
\text{ miles/min}[/tex]
We have to find the unit rate in mile per hour, so we need to multiply it by 60
Thus, unit rate is given by
Take the amount 14 MPG (miles per gallon)
Then take the number of miles to go (133 miles to go)
Divide, like so:
133/14
= 9.5
First let's set up an equation: 35+0.05t.
35 is the phone rate per month plus the number of texts (t) times 0.05 (cost of 1 text)
Now we can find the amount of texts she sent each month.
March
35+0.05t=72.60
-35 -35
0.05t=37.60
------ -------
0.05 0.05
t=752
April
35+0.05t=65.85
-35 -35
0.05t=30.85
------ -------
0.05 0.05
t=617
She sent 752 texts in March and 617 texts in April.
In 4 hours, Naoya must have read
There were 350 pages remaining at the time, so the total number of pages is
.
For each hour of reading, Naoya reads 55 pages, so the number of pages he's finished reading by the
'th hour is
. So the number of pages left to read is given by
