Answer:
805m
Explanation:
Speed = displacement/time
Speed = 23m/s
Time = 35s
Displacement = speed × time
= 23 × 35
= 805m
Answer:
1497×10⁵ km
Explanation:
Speed of light in vacuum = 3×10⁵ km/s
Time taken by the light of the Sun to reach the Earth = 8 min and 19 s
Converting to seconds we get
8×60+19 = 499 seconds
Distance = Speed × Time

1 AU = 1497×10⁵ km
The Sun is 1497×10⁵ km from Earth
