Question

Arrange the following speeds in the ascending order.

(7 m/s, 15 km/h, 2km/minute, 0.1 m/millisecond)

Answer 1

for comparing you first have see that all values must have same units.

lets convert everything in m/s

7m/s

15km/h=15(1000)m/(3600)s=4.16m/s

2km/min=2(1000)m/(60)s=33.33m/s

0.1m/millisecond=0.1/(10^-3)s=100m/s

ascending order:

15kmh<7m/s<2km/min<0.1m/millisecond
