Answer:
1. [tex]60.0 mi/h=88 feet/seconds[/tex]
2. [tex]15 Ib/inch=267.86 kg/m[/tex]
3. [tex] 6.20 cm/hr=17,222.22 nm/s[/tex]
Explanation:
1. 60.0 mi/h to ft/s
1 mile = 5280 feet
1 hour = 3600 seconds
So, [tex]60.0 mi/h=\frac{60\times 5280 feet}{1\times 3600 s}=88 feet/seconds[/tex]
2. 15 Ib/in to kg/m
1 lb = 0.453592 kg
1 inch = 0.0254 m
So,[tex]15 Ib/inch=\frac{15\times 0.453592 kg}{1\times 0.0254 m}=267.86 kg/m[/tex]
3. 6.20 cm/hr to nm/s
1 cm = [tex]10^7 nm[/tex]
1 hour = 3600 seconds
So,[tex] 6.20 cm/hr=\frac{6.20\times 10^7 nm}{1\times 3600 s}=17,222.22 nm/s[/tex]
