</span>Couches = $4 000
Reclining Chairs = $ 2 040
=> Loveseats = $2 800
So, the luxury store went on sale that makes each prices divided 4
=> Couches = 4 000 / 4 = 1 000 dollars
=> 2 couches = 2 000 dollars
=> reclining chairs = 2 040 / 4 =510 dollars

=> 3 loveseats = 2 100 dollars</span>
Since Emily is walking at a constant speed, we can solve this using proportions, equating ratios of distance/time.
The first ratio is 3/4 miles/1/4 hour
The second ratio is 1 mile/ x hour
Equating the two ratios: 3/4 / 1/4 = 1/x
3 = 1/x
x = 1/3 hour
