It takes a plane two hours to fly from detroit to new york and only an hour and thirty minutes to return. if the wind speed is 25 mph. how far apart are the two cities?

d=distance in miles   a= plane's airspeed in mi/hr

d=2(a-25)=1.5(a+25)

2a-50=1.5a+37.5

0.5a=87.5

a=175mi/hr

Plug 175 into the expression above:

2(175-25)=2*150=300

d=300 miles

One yard is 3 feet. 1 foot is 12 inches. so there's 36 inches in one yard. now, with that, 36 divided by 3 is 12. twelve 3 inch segments in one yard. using this logic, two yards has 24, three yards has 36, four yards have 46. and, four and a half yards has 52 three inch segments
