EleoNora [17]

Answer: 8.4 miles per hour

Step-by-step explanation:

Since, total distance = 24.5 miles,

Time taken = $175 \text{ minutes} = \frac{175}{60} \text{ hours} =\frac{35}{12} \text{ hours}$

Thus,

$\text{ The unit rate} = \frac{\text{ Total distance}}{\text{ Time taken}}$

$=\frac{24.5}{35/12}$

$=\frac{294}{35}$

$=8.4\text{ miles per hour}$

disa [49]

Answer:

Step-by-step explanation:

Use the point-slope formula.

y - y_1 = m(x - x_1) you have : x_1 =5 and y_1 =1

m the slope m= -1 (same slope for the line : x+y=9 because this lines are parallel and you can write y=-x+9

an equation for this line is : y-1 = -(x-5)
