Question:-
A new unit of length is chosen such that the speed of light in vacuum is unity. what is the distance between the sun and the earth in terms of the new unit if light takes 8 min and 20s to cover this distance.
Answer:-
Speed of light = 1 new unit ,
Time taken = 8 min + 20s
= 480s + 20s
= 500s
Now,
D = S/T
S*T = D
1 new unit/sec * 500s = D
D = 500 new unit
Therefore, 500 new unit it will cover.
