  • Speed of light=3×10^8m/s=3×10^5km/s
  • Distance=150million km=150×10^6km

Now

\\ \rm\longmapsto Speed=\dfrac{Distance}{Time}

\\ \rm\longmapsto Time=\dfrac{Distance}{Speed}

\\ \rm\longmapsto Time=\dfrac{150\times 10^6}{3\times 10^5}

\\ \rm\longmapsto Time=50\times 10^1

\\ \rm\longmapsto Time=500s

\\ \rm\longmapsto Time=8.33min

  • Can be written as 8min 20s.

Answer:

speed \: of \: light  = 3 \times 10 {}^{8} m \: per \: second. \\ distance = 150million \: km \\  = 150 \times 10 {}^{6} km. \\  \\ now \\ speed =  \frac{distance}{time}  \\  \frac{150 \times 10 {}^{6} }{3 \times 10 {}^{5} }  \\ 50 \times 10 {}^{1}  \\ 500sec \\ 8.33min. \\ it \: can \: be \: written \: as \\ 8min \: 20sec.

A crew of highway workers paved 1/2 mile in 1/4 hour. If they work at the same rate, how much will they pave in one hour?
mote1985 [20]

Step-by-step explanation:

The easiest approach is to realise that one hour is 3 times longer than

20

minutes. The longer the time, the more they will pave.

You could also use the 'unitary method' where you find out how much they pave in ONE minute (divide by

20

) and them multiply by

60

to find how much in one hour.
