A field of 3.9 mi2 is being subdivided into 1.3×103 family gardens. How many square miles will there be in each garden? Write the answer in scientific notation.

Answer 1

To find the number of square miles in each garden, we need to divide the total area of the field by the number of gardens.

Total area of the field = 3.9 mi²
Number of family gardens = 1.3 × 10^3 gardens

Square miles in each garden = Total area of the field / Number of gardens
= 3.9 mi² / 1.3 × 10^3 gardens

To divide by 1.3 × 10^3, we can divide by 1.3 and then multiply by 10^3.

Square miles in each garden = 3.9 mi² / 1.3 × 10^3 gardens
= (3.9 mi² / 1.3) × 10^3 gardens
= 3 mi² × 10^3 gardens

The answer in scientific notation is 3 × 10^3 mi².
