a school bus during morning pickups to calculate its average speed between 2.8 km and 4.2 km.52 km/h55 km/h42 km/h50 km/h

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
