Equation shows the relationship between distance traveled (d), speed (s), and time taken (t) is:

Solution:
Given that,
Alice traveled 30 miles in 3 hours
To find: Equation shows the relationship between distance traveled (d), speed (s), and time taken (t)
The speed is given by:

From given,
Distance = d = 30 miles
Time = t = 3 hours
Therefore,


Thus the equation is found and speed is calculated
