conversion facts for length
12 inches (in) = 1 foot (ft)
3 feet (ft) = 1 yard (yd)
36 inches (in) = 1 yard (yd)
5280 feet (ft) = 1 mile (mi)
1760 yards (yd) = 1 mile (mi)

Explanation:

Step1: Identify conversion factor

We use $5280$ feet = $1$ mile.

Step2: Convert miles to feet

Multiply height in miles by conversion factor:
$16.871 \times 5280$

Step3: Calculate and round result

Compute the product and round to nearest tenth:
$16.871 \times 5280 = 89078.88 \approx 89078.9$

Answer:
