1.	4. A particle travels with a speed of 18 km/hr, its speed in m/s is(a) 5 m/s (b) 50 m/s (C) 64.8 m/s (d) 6.48 m/s
Answer» Answer: 5 m/s Explanation: ACCORDING to the given question, speed = 18 KM/h And we know, 1 km = 1000 m 1 h = 3600 s Thus, speed = 18 km/h speed = 18×1000/3600 speed = 5 m/s Thus speed will be 5 m/s ANS.

4. A particle travels with a speed of 18 km/hr, its speed in m/s is(a) 5 m/s (b) 50 m/s (C) 64.8 m/s (d) 6.48 m/s

Answer»

Answer:

5 m/s

Explanation:

ACCORDING to the given question,

speed = 18 KM/h

And we know,

1 km = 1000 m

1 h = 3600 s

Thus,

speed = 18 km/h

speed = 18×1000/3600

speed = 5 m/s

Thus speed will be 5 m/s ANS.
