Answer:

No

Step-by-step explanation:

Given that:

Total time spent exercising = 38 minutes

Walk time = 6 minutes

Run duration = (38 - 6) = 32 minutes

Running rate = 8 minutes per mile

Number of miles covered over 32 minutes :

Running rate per minute ; Miles covered per minute :

1 / 8 miles

Total Miles covered :

Rate * duration

1/8 * 32

= 4 miles

From the result above, Matteo is wrong as he will only cover 4 miles during the period.
