Took about three days to arrive from 149597870.691 kilometers (1 A.U) away.
Do the math and post a reply with the speed in Kilometers per hour and Miles per hour.

UPDATE:

Here’s some quick math from Susan in Tennessee:

2,077,748.2 km/hr or 1,291,053 mi/hr
Making the assumption that it takes a full three days…

3 days * 24 hr/day = 72 hr
149,597,870.691 km / 72 hr = 2,077,748.204 km/hr

…To convert…
There are 0.62137 miles in a kilometer, so
2,077,748.204 km/hr * 0.62137 mi/km = 1,291,050.401 mi/hr

You’ll have to excuse my not worrying about significant digits and such

If we take Susan’s 2,077,748 km/hr and divide by 60, then take the result and divide by 60, we get 577 km/sec
Solar wind is between 400 and 700 km/sec. Keep in mind people, these are really rough numbers, but they are pretty close.
