<u>Answer: </u>

Option (c)

The average speed between 2.8 km and 4.2 km is 42 km/h

<u>Explanation:</u>

Given, the distance between 2.8 km and 4.2 km is 4.2 - 2.8 = 1.4 km

Time (in hours) between 2.8 km and 4.2 km

    = 0.084 – 0.051

     = 0.033 hr

Speed =\frac{Distance}{Time}

Speed = \frac{1.4}{0.033}

Speed = 42.4 km/hr = 42 km/h (rounded to nearest)

Therefore, the average speed between 2.8 km and 4.2 km is 42 km/hr

Hence, Option (C) is correct

Eric earned 60 points on his last test if there were 75 possible points what was his percent grade
Andru [333]
So 75 points is your 100%. You can do 60 over 75 is equal to X over 100. You divide your numerator(60) by your denominator(75) to get 85.7142857%, or to round to your nearest percent, your answer would be roughly 86%.
