Question

las convercines expresar 45 km/ hr en pies/ seg​

Answer 1

Explicación paso a paso:

Para convertir de km/hr a pies/seg, requeriremos los siguientes datos:

1 km = 1000 m

1 m = 100 cm

2.54 cm = 1 in (pulgadas)

12 in = 1 pie

1 hr = 60 min

1 min = 60 seg

45 km / hr = x pies / seg

Entonces:

x = $(45 \frac{km}{hr} )(\frac{1000m}{1 km} )(\frac{100cm}{1m})(\frac{1in}{2.54cm})(\frac{1pie}{12in})(\frac{1hr}{60min})(\frac{1min}{60seg})$

x = $\frac{(45)(1000)(100)}{(2.54)(12)(60)(60)} \frac{pie}{seg}$

x = 41.01 pie/seg     =====> Solución
