The Correct answer to this question for Penn Foster Students is: 137.5 m

Alisa Newton · Answer 2

Answer is B. According to the equation of motion s = vt + 1/2 at2 Where s is distance covered, v is velocity, a is acceleration and t is time taken. So, by putting all the values, we get s = (20) (5) + 1/2 (3) (5) 2 s = 100 + 1/2 (3) (25) s = 100 + 1/2 75 s = 100 + 37.5 s = 137.5 meters
