An ISRO Earth observation satellite takes $90\text{ minutes}$ to complete one full orbit around Earth. How many complete orbits will it complete in $24\text{ hours}$?
$12$
$16$
$18$
$24$
Solution
In 24 hours, there are $24 \times 60 = 1440\text{ minutes}$. Dividing $1440$ by $90$ yields $16$ orbits.
