Answer:
Option D is the correct answer.
Explanation:
Height of grass = 5.08 x 10⁻⁵miles
Feet
1 mile = 5280 feet
Height of grass = 5.08 x 10⁻⁵x 5280 = 0.268 ft
Kilometers:
1 mile = 1.6 km
Height of grass = 5.08 x 10⁻⁵x 1.6 = 8.128 x 10⁻⁵ km
Meters:
1 mile = 1600 m
Height of grass = 5.08 x 10⁻⁵x 1600 = 0.0812 m
Inches:
1 mile = 63360 inches
Height of grass = 5.08 x 10⁻⁵x 63360 = 3.22 inches
From seeing the result it can be understood that inch is the best unit to measure the height of grass.
Option D is the correct answer.
