Question

A body moving along straight line covers a distance
in three equal parts with speed 2 m/s, 3 m/s and
4 m/s, then its average speed is​

Answer 1

$average \: speed = \frac{ v1 + v2 + v3}{3} \\ v1 = 2m {s}^{ - 1} \\ v2 = 3m {s}^{ - 1} \\ v3 = 4m {s}^{ - 1} \\ \\ average \: speed \: = \frac{2 + 3 + 4}{3} \\ = \frac{9}{3} \\ = 3m {s}^{ - 1}$

Hope that helps✌️☺️
