Answer:

1.5 m/s

Step-by-step explanation:

To find the rate of change for two different sets of data, you have to divide the distance and the time to find the speed.  

Using the general formula: d = rt, where d=distance, r=rate and t=time,

r = d/t

[tex]\frac{distance}{time}=\frac{meters}{second}=\frac{75}{50}=1.5m/s[/tex]
