Explanation:
4. converting 80km/hr to m/sec we get, 80×(5/18) m/sec whose value is 22.22m/s .
so, it can be clearly seen that, the bike is moving with a greater speed.
5.simmi's speed = 800/180
= 4.44 m/sec
Garima's speed = 2000/2400
= 0.833 m/s
so, comparing their indivisual speeds, we can see Simmi is running at a faster rate.
have a nice day
