Earth is 150 million kilometers from the sun, and the solar "wind" travels at about 400 km/sec. How long does it take particles
FrozenT [24]

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.
