Sorry, no help here. Those questions on the math test that read, "if you left New York at 9 and travelled to Boston, stayed for 2 hrs. and travelled to Florida...What time would you get there?" I actually answered one, "Who cares?" The only way I could figure out the block would be to draw out the original on graph paper and see if I could deduct 8 squares off of the pieces. (8 1/4 inch squares =2 inches?)
