Answer 1

Record = 24 ft 9 1/4 in = 24' 9.25". Bruce = 24' 1 1/2" = 24' 1.5". Nominal difference = 9.25 − 1.5 = 7.75" = 7 3/4".

Because measurements are to the nearest 1/4", Bruce must exceed the record by half a quarter (1/8") to be recorded larger. So add 1/8":

7 3/4" + 1/8" = 7 7/8".

Answer: 7 7/8 inches.
