11. How long does it take my mum to walk 5 metres if she is travelling at a speed of 1 km/h. (Hint to change metres to kilometres divide the metres by 1000)

Answer: The time taken by mother to walk is 0.005 hrExplanation:Speed is defined as the rate at which an object moves with respect to time.To calculate the time taken for the given speed, we use the equation:[tex]s=\frac{d}{t}[/tex]where,s = speed of the mother = 1 km/hrd = distance traveled = 5 m = 0.005 km    (Conversion factor:  1 km = 1000 m)t = time taken by mother = ?Putting values in above equation, we get:[tex]1km/hr=\frac{0.005km}{t}\\\\t=\frac{0.005km}{1km/hr}=0.005hr[/tex]Hence, the time taken by mother to walk is 0.005 hr

First convert 1km/h to .28m/s then divide your 5m by .28m/s to get about 18seconds.View attachment for detailed steps.
