Respuesta :

70/80 = 0.857 miles per minute

Answer: d. 0.875 miles 

Answer:

The average speed per minute of the car is :

d. 0.875[tex]\frac{mi}{min}[/tex]

Step-by-step explanation:

The average speed tells you the speed of an object over time, it can be expressed as:

[tex]A_{s}=\frac{Distance}{Time}[/tex]

As the car travels 70 miles in 80 minutes, we can replace values in the equation:

Distance = 70 miles

Time = 80 minutes

[tex]A_{s}=\frac{Distance}{Time}[/tex]

[tex]A_{s}=\frac{70miles}{80minutes}[/tex]

[tex]A_{s}=0.875\frac{mi}{min}[/tex]
