Question

Matteo spends a total of 38 min exercising. He walks for 6 min to warm up and then runs at a constant rate of 8 min per mile for the rest of the time. Matteo says that he ran 4.75 mi. Is he correct?

Answer 1

No, he not correct because he only ran 4 mi

Explanation:

If he walks for 6 min out of the 38 min, then he ran for 32 min.

d = rt 1 mi = 8r

r = 1/8 = 1 mi/8 min Since he ran 32 min we have

d = 1/8(32) = 4 mi.

No, he not correct because he only ran 4 mi
