Answer:
40+75 x = 125 + 25x
Step-by-step explanation:
Rosa runs 3 miles in 42 minutes.
I divided 42 by 56 to get the percentage that will be multiplied to 4 miles to get the number of miles Rosa runs in 42 minutes.
42 / 56 = 0.75 * 100% = 75%
75% * 4 miles = 3 miles.
3 miles within 42 minutes
X (X - 1) = 342
x² - x = 342
x² - x - 342 = 0
X = 19
