Question

which is greater--- a Speed of 30 m/ sec or 30 km / h​

Answer 1

Step-by-step explanation:

30km/h or 30 km h‐¹ is the correct answer

Answer 2

30m/s is Greater

Procedure

• Convert it to km/h by multiplying with 18/5 you will get 108 km/h which is greater than 30km/h.

SOLUTiON

1 m/s = 0.001 km / (1/3600) hour

1 m/s = 3.6 km/h

∴ 30 m/s = 30 x 3.6 km/h

= 108 km/h

∴ 108 km/h > 30 km/h

So, 30 m/s is greater than 30 km/h.
