If a day on Mars is 9.98 x 10^4 sec long, how many earth days are in a Mars' day?

mr Goodwill [35]

Use the next convertion factors:

60 seconds are equal to 1 minute

60 minute are equal to 1 hour

24 hours are equal to 1 day in earth

$9.98\times10^4s\cdot\frac{1\min}{60s}\cdot\frac{1h}{60\min}\cdot\frac{1\text{day}}{24h}\approx1.15\text{day}$ <h2>Then, there are approximately 1.15 earth days in a Mar's day</h2>
