An ISRO satellite receives a command signal sent from a ground station in Sriharikota. If the signal takes $0.12\text{ seconds}$ to travel one-way from the station to the satellite, how many seconds will it take for a signal to make a complete round trip (station to satellite and back)?
$0.24\text{ seconds}$
$0.12\text{ seconds}$
$0.36\text{ seconds}$
$0.48\text{ seconds}$
Solution
A round trip covers twice the one-way distance, so the total travel time is $0.12\text{ seconds} \times 2 = 0.24\text{ seconds}$.
