Question

Convert the following: 1. 60.0 mi/h.to ft/s 2. 15 Ib/in2 to kg/m? 3. 6.20 cm/hr2 to nm/s

Answer 1

1.
`60.0 mi/h=88 feet/seconds`

2.
`15 Ib/inch=267.86 kg/m`

3.
`6.20 cm/hr=17,222.22 nm/s`

Step-by-step explanation:

1. 60.0 mi/h to ft/s

1 mile = 5280 feet

1 hour = 3600 seconds

So,
`60.0 mi/h=(60* 5280 feet)/(1* 3600 s)=88 feet/seconds`

2. 15 Ib/in to kg/m

1 lb = 0.453592 kg

1 inch = 0.0254 m

So,
`15 Ib/inch=(15* 0.453592 kg)/(1* 0.0254 m)=267.86 kg/m`

3. 6.20 cm/hr to nm/s

1 cm =
`10^7 nm`

1 hour = 3600 seconds

So,
`6.20 cm/hr=(6.20* 10^7 nm)/(1* 3600 s)=17,222.22 nm/s`
