To find the width of the park, we need to divide the area by the length of the park.

Area = 1.36×10^8 ft^2
Length = 1.6×10^4 ft

Width = Area / Length
Width = (1.36×10^8 ft^2) / (1.6×10^4 ft)

To divide two numbers in scientific notation, we subtract the exponents:
Width = 1.36×10^(8-4) ft
Width = 1.36×10^4 ft

Therefore, the width of the park is 1.36×10^4 ft, which is equivalent to 8.5×10^3 ft.

The correct answer is 8.5×10^3 ft.
