Question

if a day on venus is 9.98 x 10^4 sec long. how many earth days are in a venus day?

a. 1.16 x 10^3 days

b. 1.026 days

c. 1.16 days

d. 32.2 days

e. none

Explanation:

Step1: Know the number of seconds in an Earth - day

There are 24 hours in a day, 60 minutes in an hour and 60 seconds in a minute. So the number of seconds in an Earth - day is $24\times60\times60=86400$ seconds.

Step2: Calculate the number of Earth - days in a Venus - day

We know a Venus - day is $9.98\times 10^{4}$ seconds long. Let $x$ be the number of Earth - days in a Venus - day. Then $x=\frac{9.98\times 10^{4}}{86400}$.
$9.98\times 10^{4}=99800$, and $\frac{99800}{86400}\approx1.16$.

Answer:

C. 1.16 days
