Answer:

Option (c)

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

Explanation:

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 =[tex]\frac{Distance}{Time}[/tex]

Speed = [tex]\frac{1.4}{0.033}[/tex]

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
