Answer:
5 miles / Maria's time = 4 miles / Gus's time
Since both Maria and Gus run for equal periods of time, we can set their times equal to each other:
5 miles / t = 4 miles / t
where t is the time it takes both of them to run.
Simplifying this equation, we can see that the distance Maria runs (M) is equal to the distance Gus runs (G) multiplied by 5/4:
M = (5/4)G
Therefore, the correct equation that relates the variables defined is:
M = (5/4)G
This means that Maria's distance is 1.25 times Gus's distance. So, the correct answer is option B: M = 1.25G.
