Using Pythagoras Theorem
<u>The correct option is C</u>
<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 =
Speed =
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
