The required speed in km/hr are 108km/hr and 25.704km/hr
Given the following conversion rate
Given that the speed of cheetah is 30meters per second. Converting to m/s will give:
30m/s = [tex]\frac{30m}{1s} \times \frac{1km}{1000m} \times \frac{3600s}{1hr} \\[/tex]
30m/s = 30 * 3.6
30m/s = 108km/hr
For the person with speed of 7.14m/s, the value in km/hr is expresssed as:
7.14m/s = 7.14 * 3.6
7.14m/s = 25.704km/hr
Hence the required speed in km/hr are 108km/hr and 25.704km/hr
