We have that the new speed after she picks up her child is mathematically given as

V2=3m/s

<h3>Speed</h3>

The speed of a body is simply the rate at which the body moves or functions, the speed of a body is measured with an SI unit of m/s.

Generally the equation for the Velocity is mathematically given as

m1v1=m2v2

Therefore

$v2=\frac{60*4}{60+20}$

V2=3m/s
