How far does light travel in $1.0 \mu \mathrm { s }$ ? $\left( c = 3.0 \times 10 ^ { 8 } \mathrm {~m} / \mathrm { s } \right)$
A) $0.30 \mathrm {~km}$
B) $3.0 \times 10 ^ { 14 } \mathrm {~m}$
C) $3.0 \mathrm {~m}$
D) $30 \mathrm {~cm}$

Quizplus · Accepted Answer

Light travels $3.0 \times 10^8 \mathrm{~m/s}$. In $1.0 \mu s = 1.0 \times 10^{-6} s$, it travels $3.0 \times 10^8 \times 1.0 \times 10^{-6} = 0.3 \mathrm{~m}$, which is $0.30 \mathrm{~km}$.
