Speed = distance ÷ time.
= 600÷(5×60),
= 2 m/s.
Speed in km/hr:
= 2×(18/5),
= 7.2 km/hr.
= 600÷(5×60),
= 2 m/s.
Speed in km/hr:
= 2×(18/5),
= 7.2 km/hr.

Speed = Distance ÷ time.
Speed = 600÷(5×60).
Speed = 2 m/sec,
Now, convert into kmph.
i.e.,S = 2×(18÷5).
Then S = 7.2 kmph.
Speed = 600÷(5×60).
Speed = 2 m/sec,
Now, convert into kmph.
i.e.,S = 2×(18÷5).
Then S = 7.2 kmph.
