Answer 2

Answer:

72 km per hour

Step-by-step explanation:

To compare 1 km/h and 1 m/s, first let us bring them to a common unit. If we convert 1 m/s to km/h, we get, 1 m/s = 3.6 km/h. Now, it is easy to compare 1 km/h and 3.6 km/h, which shows that 3.6 km/h is a faster speed. Hence, 1 m/s is faster than 1 km/h.
