**MathMate**, Sunday, October 4, 2009 at 5:56pmArithmetic:

Clipper's lead = 8 knots * (1/2) hour = 4 nautical miles

For each hour, the Rover catches up by (10-8)=2 nautical miles.

Time required to catch up = 4/2 hours (after 9:30)

Time the Rover will catch up = 11:30

Algebra:

Let t=time (as of 9:30) to catch up

10*t - 8*t = 8*(1/2)

2t = 4

t=2

The Rover will catch up at 11:30.
