Question
How many seconds does Puja take to cover a distance of 500 m, if she runs at a speed of 30 km/hr?
Solution
Step 1: Convert speed from km/hr to m/s We know that 1 km = 1000 m and 1 hour = 3600 seconds. So, 30 km/hr = 30 * (1000/3600) = 8.33 m/s
Step 2: Use the formula of time We know that time = distance/speed. So, time = 500 m / 8.33 m/s = 60 seconds.
Therefore, Puja takes 60 seconds to cover a distance of 500 m at a speed of 30 km/hr.
