Answer 1

Answer:

To convert 320 km in meters multiply it by 1000

and to convert hour in seconds multiply it by 60*60

so (320*1000)/(60*60)=88.88 m/s

for 150 m/s

convert 150 in km and second in hour

so (150/1000)/(1/60*60)=540 km/h

Answer 2

Answer:

1) 88.9m/s

2) 540km/h

Explanation:

1) 320km/h

1km = 1000m

1h = 3600s

∴ 320$\frac{km}{h}$ = $\frac{320 * 1000}{3600}$ ≈ 88.9m/s

2) 150m/s

1m = $\frac{1}{1000}km$

1s = $\frac{1}{3600} h$

∴ 150$\frac{m}{s}$ = $\frac{150 * 3600}{1000}$ = 540km/h
