Answer:
Step-by-step explanation:
Given parameters:
1 mile = 6 x 10⁴ inches
Average human hair = 3 x 10⁻³ inches
Unknown:
How many times longer is a mile than a human hair;
Solution:
Since we know that a mile 6 x 10⁴ inches , we can compare this quantity to the human hair;
Number of times = [tex]\frac{6 x 10^{4} }{3 x 10^{-3} }[/tex]
Number of times = 2 x 10⁴⁺³
Number of times = 2 x 10⁷
So, a mile is 2 x 10⁷ times longer than the human hair.
