the school record for sailing a paper airplane is 30 feet 9 inches.Paul sailed his airplane 7 yards 2 feet 6 inches.How far short of the record was his flight?

Respuesta :

convert yards to feet
1yard=3ft
times both sides by 7
7 yards=21ft

7yards 2ft, 6in is
21ft+2ft and 6in or
23ft and 6in


so from 23ft 6in to 30ft 9 in is how much?
30ft, 9in-23ft, 6in=
30ft-23ft, 9in-6in=
7ft, 3in


he was 7ft, 3in short
