Hey Julie, the time taken is calculated by the equation time = distance/speed. So you can divide 150,000km by 460,000 km/sec to get the answer

$$\prod_{?}^{?}$$

OpenStudy (sandra):

very cool!

OpenStudy (sandra):

The distance from earth to sun is 93,000,000 miles, and a km is less than a mile. I think we should revisit the original problem!

i dont know

There's something wrong with the original problem. The speed of light is 299,792 km/sec. If a textbook said 460,000 then it is *wrong*. This would change the answer...
