Ellen's house is farther from Haley's because 1.41 miles = 7444.8 feet. It is also 898 feet farther away because 7444.8-6547 = 897.8, then you round to the nearest foot, giving you 898 feet.
Y = k/x is the inverse equation.
6 = k/11
Solving for k, multiply by 11 on both sides.
66 = k
y = 66/x
13.2 = 66/x
x = 5
