PLEASE HELP ME?

A scale model of a Boeing 747passenger jet is 14.12 cm long and has a wingspan of 11.92 cm. The model was made at a scale factor of 1/500 . What are the dimensions of a hangar that could fit three of these passenger jets side by side, if the jets need 10 m clearance around them on all sides?

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

so in 1 hour   it can travel 30 miles
