Answer:
The correct answer is - 4.34 days.
Explanation:
Given:
Distance from the sun to earth = 150 million kilometer
= 1500,00,000 km
The solar "wind" travels = 400 km/sec
= 400*60*60 km/ hour
= 1440000 km/hour
Then time = distance/speed
time = 1500,00,000 km/1440000 km/hour
time = 104.166666667 hours
time = 104.166666667/24
= 4.34 days.
