Question

arrange the following speed in increasing order 7 meter per second, 15 km per hour and 2 km per minute

Answer 1

the increasing order is 2km per minute <7meter per sec<15km per hour

Answer 2

convert all in m/s

7m/s
$15kmh {}^{ - 1} \\ 15 \times \frac{1000}{3600} \\ 4.16m {s}^{ - 1}$
$2km {min}^{ - 1} \\ 2 \times \frac{1000}{60} \\ 33.3m {s}^{ - 1}$

2km/min >7m/s>15km/h
