Question

What is 5.6 × 10^−3 yd/year in feet per day?  

Answer 1

5.6x10^-3 yd/year in feet per day.

There are 3 feet in a yard

(5.6x10^-3)x3=1.68x10^-2 feet/year
Let's take there to be 365 days in the year (Fun fact: The actual duration of our year is 365 days 5 hours, 48 minutes 46 seconds)

$\frac{1.68*10^{-2}}{365} = 4.6*10^{-5}$

Therefore the correct answer is D.
