Question

Speed of light in S.l. system is 3 * 10 m/s. In a
new system, unit of length is a km and unit of
time is b second. Then speed of light in new
system of unit is​

Answer 1

Answer:

$3 \times 10 {}^{5} \times \frac{b}{a}$

Explanation:

Speed of Light in SI system = 3 × 10^8 m/sec

Light covers a distance of 3 × 10^8 m in 1 sec

Therefore,

It covers in 1 sec.

$\frac{3 \times 10 {}^{8} }{ {a \times 10}^{3} }$

Hence it covers

in b sec

$3 \times {10}^{5} \times \frac{b}{a}$
