C. [tex]5 \times 10^{-6}[/tex] ft/day
D. [tex]4.6 \times 10^{-5}[/tex] ft/day
Please explain the answer.
Answer (2)
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)
365 1.68 ∗ 1 0 − 2 = 4.6 ∗ 1 0 − 5 Therefore the correct answer is D.
The conversion from 5.6 × 1 0 − 3 yd/year to feet per day results in approximately 4.6 × 1 0 − 5 ft/day. Therefore the correct answer is D. This is done by first converting yards to feet and then dividing by the number of days in a year.
