How many seconds does Puja take to cover a distance of 500 m, if she runs at a speed of 30 km/hr?A)40secB)60secC)44secD)55sec
Question
Solution 1
First, we need to convert the speed from km/hr to m/sec.
We know that 1 km = 1000 m and 1 hour = 3600 seconds.
So, 30 km/hr = 30 * (1000/3600) = 8.33 m/sec.
Now, we can find the time taken to cover 500 m.
Time = Distance / Speed
So, Time = 500 m / 8.33 m/sec = 60 seconds.
