- answer is 7.2 because speed formula is distance/time so 600/5=120
but we mention in km/hour so answer is 7.2 - 12 years agoHelpfull: Yes(6) No(2)
- Answer: Option B
Explanation:
Speed = 600 m/sec.
5 x 60
= 2 m/sec.
Converting m/sec to km/hr (see important formulas section)
= 2 x 18 km/hr
5
= 7.2 km/hr.
