The average speed is 10 m/s.

Explanation:

The motion of the object is divided into two parts.

In the first part, the object covers a distance of

$d_1 = 100 m$

In a time interval of

$t_1 = 4 s$

In the second part, the object is a t rest, so it covers a distance of

$d_2 = 0$

In a time interval of

$t_2 = 6 s$

The average speed for the trip is given by the ratio between the total distance and the total time taken, therefore:

$s=\frac{d_1+d_2}{t_1+t_2}=\frac{100+0}{4+6}=10 m/s$
