Answer:
18 km/h < 10 m/s < 1 km/min
Explanation:
As all the above speeds are in different units. Therefore first of all we convert them into same units. For example we convert them into SI units.
18 km/h = 18 × 1000m / 3600sec
18 km/h = 5 m/sec
10 m/sec = 10 m/sec
1 km/min = 1 × 1000m / 60sec
1 km/min = 16.67 m/sec
So Increasing Order of speed becomes:
18 km/h < 10m/sec < 1 km/min
