How do you find average speed with distance and time?
Divide the distance by the time.
This will give you the average speed per unit of time, usually hour. So, if Ben traveled 150 miles in 3 hours, his average speed is 50 miles per hour
How do you find average speed with hours and minutes?
How to calculate average speed. Speed is distance divided by time. Simply put, if you drove 60 kilometer's for one hour, it would look like this: Speed = distance (60 km) / time (1 hour) = 60km/h.

Answer:
(x,y) = (-2, -1)
Step-by-step explanation:
We start off by substituting the value of "x".
5x+7y=-17
x=-![\frac{5}{4} + \frac{3}{4}y](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7B4%7D%20%2B%20%5Cfrac%7B3%7D%7B4%7Dy)
We then solve 5![5(-\frac{5}{4}+\frac{3}{4}y ) +7y= -17](https://tex.z-dn.net/?f=5%28-%5Cfrac%7B5%7D%7B4%7D%2B%5Cfrac%7B3%7D%7B4%7Dy%20%29%20%2B7y%3D%20-17)
y=-1 *Substitute the value of "y"
x= -![-\frac{5}{4}+\frac{3}{4}x(-1)](https://tex.z-dn.net/?f=-%5Cfrac%7B5%7D%7B4%7D%2B%5Cfrac%7B3%7D%7B4%7Dx%28-1%29)
x=-2
This works.
Using the inequality
2.50x + 3.50y ≤ 30
substituting y with the number of cheeseburgers sold
2.5x + 3.5(4) ≤ 30
x = 6.4
The maximum number of hamburgers he can sell is 6
