The average speed between t = 1.0 s and t = 4.0 s will be 2.1+0.3 which is 2.4m/s
<h3>
Velocity function </h3>
Given the equation for the position of the mouse expressed as:
The velocity of the particle is expressed as:
Given that p = 0. 40 m/s and q = -1. 10 m/s, the equation will become:
If the time is <em>t = 1.0 s, the velocity will be:</em>
Similarly if t = 4.0ssec, hence:
The average speed between t = 1.0 s and t = 4.0 s will be 2.1+0.3 which is 2.4m/s

Complete question
<em>A mouse runs along a baseboard in your house. The mouse's position as a function of time is given by x(t)=pt 2+qt, with p = 0.40 m/s2and q = -1.10 m/s . Determine the mouse's average speed between t = 1.0 s and t = 4.0 s. I have tried everything and the answer is not 0.40 m/s</em>
