An MTV was 0.083 meters long, had a mass of 0.0292 kilograms, and it crossed a distance of 24.625 meters. Suppose the mousetrap vehicle operated...

Speed of an object is given as the ratio of distance traveled to time taken. That is,

Speed = distance/time

Here, the mousetrap vehicle or MTV covered a distance of 24.625 meters in a time duration of 16 seconds. That is,

Distance = 24.625 m

Time = 16 s

Hence, the speed of MTV can be calculated as:

Speed = 24.625/16 m/s = 1.54 m/s

The average speed is not related to mass and length of the object and is solely the function of distance traveled and time taken. 

We can also calculate the acceleration achieved by the crusaders mousetrap vehicle, by making a simple assumption: the MTV started from rest. Since acceleration is the rate of change of velocity, it can be calculated as:

acceleration = change in velocity/time = (1.54-0)/16 = 0.096 m/s^2.

Hope this helps.
