Alright we are going on a Journey to Uranus and only have 3 weeks, 21 days, or 504 hours. First thing we need is the average distance from Uranus to the sun which is about 1,783,950,480 miles, or 19.218 AU. Now we minus that distance from the distance to the Earth and the sun and we get 1,690,950,480 miles closest distance from the Earth to Uranus. Now we know how far we need to go, next we need to find out how fast we need to get their in 3 weeks so we take 1,690,950,480 and divide it by how many hours we have, which is 504. This equals 3,355,060.5 miles we have to travel each hour. We than divide this by 60 to give us the miles per second we have to travel giving us 55,917.7. At this number we can deduce that given the light constant of 180,000 miles per second we find that to get from the earth to Uranus at their closest points to each other we would have to travel at 31.065% the speed of light to reach Uranus in 3 weeks.
Divide the 90 miles by 3600. That's the amount of miles you travel in a second. Then convert this from miles to feet.

800,000 seconds per minute Light travel approximately 3x10^8 ms-1 or approx 186,000 miles/second.
75 miles per hour = 110 feet per second
Migrating hummingbirds fly at a speed of about 25 miles per hour. so that's about 0.0069 miles per second
