we know that speed of the radio signals is 3×10^8 m/s because it is a electro magnetic wave
speed = V = 3×10^8 m/s
time = t = 1.27 sec
distance = d = ?
V = d/t
V×t = d
3×10^8×127×10^-2 = d
381×10^8-2 = d
381×10^6 m = d
so the distance between moon and Earth is 381×10^6 metre
speed = V = 3×10^8 m/s
time = t = 1.27 sec
distance = d = ?
V = d/t
V×t = d
3×10^8×127×10^-2 = d
381×10^8-2 = d
381×10^6 m = d
so the distance between moon and Earth is 381×10^6 metre

Ans is 3.81 x10^5 how it comes
ans is 381 × 10^6 m in [km 381 × 10^3 km ] 3.81 × 10^5 is equal s to 381×10^3 km. so you can also ans is 3.81×10^5 km. or 3×10^6 m
3.81×10^5 = 381×10^-2×10^5 = 381×10^5-2 = 381×10^3 km
3×10^6 m in km 3×10^3 km
