Respuesta :

B, this is because if you times 50 miles and 1 hour by 8, you will get 400 miles and 8 hours.

Answer: Option 'B' is correct.

Step-by-step explanation:

Since we have given that

Distance traveled by Ariel= 400 miles

Time taken by her = 8 hours

Since we know that rate of change is the number of measurement is being compared.

We need to calculate the rate of change is given by

[tex]Rate=\frac{Distance}{time}\\\\Rate=\frac{400}{8}\\\\Rate=50\text{ miles per hour}[/tex]

So, Rate of change is 50 miles per hour

Hence, Option 'B' is correct.
