A=b/4√4a^2-b^2

or,A=16/4√4(8)^2-(16)^2

or,A=4√4*64-256

or,A=4√256-256

or,A=4√0

or,A=4*0

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour
