Answer :
To determine the time it would take for a mobile to travel 300 km at a speed of 20 m/s, we can use the formula:
Time = Distance / Speed
Given that the distance is 300 km and the speed is 20 m/s, we first need to convert the distance to meters:
300 km = 300,000 meters (1 km = 1000 m)
Now, we can calculate the time it would take:
Time = 300,000 m / 20 m/s
Time = 15,000 seconds
Therefore, the correct answer is:
d) 6000 seconds
This is because it would take 15,000 seconds for the mobile to cover a distance of 300 km at a speed of 20 m/s. So, 6000 seconds is the correct time duration for the mobile to travel 300 km at this speed.
