Explanation:

Step1: Calculate the perimeter of the rectangular park

The formula for the perimeter of a rectangle is $P = 2(l + w)$, where $l = 150$ yards and $w=125$ yards. So $P=2(150 + 125)=2\times275 = 550$ yards.

Step2: Find the distance Debbie walks in two rounds

If she walks around the park two - times, the distance $d$ she walks is $d = 2\times P$. Substituting $P = 550$ yards, we get $d=2\times550 = 1100$ yards.

Step3: Calculate the number of times she needs to walk to cover 1,000,000 yards

Let the number of times be $n$. We know that the distance per round is $P = 550$ yards and the total distance is $1000000$ yards. So $n=\frac{1000000}{550}=\frac{100000}{55}=\frac{20000}{11}\approx1818.18$. Since she can't walk a fraction of a time, she needs to walk 1819 times.

Answer:

a. 1100 yards
b. 1819 times
