=>. 60 km / hr = { 60 × 5 / 18 } m / s

Answer:
a)50/3 m/s b)15 m/s 1)16/18 m/s 2)Tony
Step-by-step explanation:
when we have to convert km per hour in m/s then we have to multiply it by 5/18
in question 1 we know that speed = distance/time.we have to convert minutes in seconds because we know that S.I unit of speed is m/s.
same process is done in question 2 .
