ok well you would set up an equation 7miles/50 mins=xmiles/75mins then you would cross multiply 7*75=50x
then you simplify 525=50x
then divide both sides by 50 and you end up with 10.5
so she would run 10.5 miles in 75 minutes

Answer:
231
Step-by-step explanation:
Given

Cross Multiply

Therefore x=231
Area = 2310 ft * 535 ft = 1 235 850 ft²
43560 ft² = 1 acre.
1 235 850 ft² = 1 235 850/43560 ≈ 28.371 acres.
