Light travels at the speed of 3,00,000 km per second. Light from the sun reaches us in 8 minutes. If a supersonic jet were to travel from the sun at the speed of 1000 km per hour, approximately how long would it take to travel the same distance?

Answer:
The process by which the sun's radiation reflected from the earth surface is trapped buy some gases.
Answer:
The time taken to travel the same distance is 17 years.
Explanation:
Time = 8 minutes = 8×60
= 480 sec
Speed of the jet = 1000 km per hour
The distance is calculated using the formula
Distance = speed × time
= 3 × 10⁵ × 480
= 1440 × 10⁵ km
The time taken to travel the same distance = Distance/speed
= 1440×10⁵/1000
= 144000 hr
One year = 8760 hours(365×24 hours)
Thus, one hour = 1/8760
= 0.000114155 years
One hour = 0.000114155 years
Therefore, 144000 hour = 144000×0.000114155
= 16.438 years
≈ 17 years
The time taken to travel the same distance is 17 years.
