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.
