#20# times

Explanation:

If the Wright brothers' first flight was #30mph#, a Boeing #747# cruises at #600mph#, and you want to find how much faster the #747# flies compared to the Wright brothers' first flight, then divide #600# by #30#.

#(600mph)/(30mph)#

#=color(green)(|bar(ul(color(white)(a/a)20color(white)(a/a)|)))#

#:.#, the flight speed of the #747# is #20# times faster.
