#5.75# hours, or #5# hours and #45# minutes.

Explanation:

Set up a proportion. They are asking "miles per hour" or:

#"miles"/"hours"#

So Jeremy is traveling #60# miles in #1# hour, and his flight is #345# miles in #x# hours:

#60/1 = 345/x#

These two things are equal to each other, because they are proportional.

To solve for #x#, first cross multiply. The ones being multiplied together are colored the same:

#color(blue)60/color(green)1 = color(green)345/color(blue)x#

#60(x) = 1(345)#

#60x = 345#

#x = 5.75#

So Jeremy's flight lasted #5.75# hours. This is the same as #5# hours and #45# minutes.
