**Steve**, Sunday, April 7, 2013 at 6:47pmAssuming Kathy is a Formula-1 racer, driving 510km in 1 hour,

time = distance/speed

add up the times:

250/x + 360/(x+10) = 1

x = 604.13 km/hr - a new world land speed record!!!!

If 1 hour is not the correct time, then fix it and solve the new equation.
