Question

please give answer of this two questions
And please don't give wrong answers ​

Answer 1

3. a. Given,

= 1 km/hr = 5/18 m/s

= 0.277777.... m/s

= 0.278 m/s (approx.)

3. b. Given,

= 18 km/min

= (18*60) km/hr

= 1080 km/hr

= (1080*5)/18 m/s

= 5400/18 m/s

= 300 m/s

4. Given,

If we need to arrange the Speeds in their ascending order, we need to convert them into a common unit at first, like all in m/s,

10 m/s, (1*60*5)18 m/s, (18*5)/18 m/s

10 m/s, 16.67 m/s, 5 m/s

So, the increasing order is:

5 m/s < 10 m/s < 16.67 m/s

18 km/hr < 10 m/s < 1 km/min

I hope this helps.
