1) Solve for x:

0 = x^0.5 + 1

2) How far did the hummingbird fly?

Two trains, A and B, are 5 miles apart, each traveling at 60 MPH, heading towards each other on the same track. At that precise moment, a hummingbird at the front of Train A is frightened and flies 90 MPH straight towards Train B. Upon meeting Train B, the hummingbird immediately turns around and flies back towards Train A at 90 MPH. The pattern is repeated until the two trains collide and smash the poor bird. How far did the bird fly between the two trains before it died?
