Verified Answer :

Distance = Speed x Time, we are going to derived our equation.

 You can compute for the average speed using the equation: speed = distance ÷ time.

 So plugging in our data, it will look like:

 Speed = distance / time

 = 100 m / 50 s

 = 2 m/sec

 Juan average speed is 2 m / sec.
