The distance between town X and Town Y is equal to the difference between the distance between Town X and Town Z and the distance from Town Y and Town Z. Mathematically d (X-Y) = d (X-Z) - d(Y-Z) Substituting, d(X-Y) = 57 miles - 28 miles = 29 miles Thus, the distance from Town X to Town Y is 29 miles.
<span>Towns X, Y, and Z are on the same straight road. Town Y is between Town X and Town Z. Town X is 57 miles from Town Z, and Town Y is 28 miles from Town Z. </span><span>Total distance=57 miles. Subtract the distance from y to z </span><span>57 miles - 28 miles = 29 miles</span> Hence, The distance from Town X to Town Y is 29 miles. I hope it helps. Thank you
