# A hot air balloon moves at a rate of 38 km per hour. At this rate, how long will it take to fly 190 km?

5 hours

#### Explanation:

turn the problem into an equation:
$y = 38 x$
$x$ being the hours and we want to know how many hours we need to go until reach 190 km.
$190 = 38 x$
solve for hours $x$
$x = \frac{190}{38}$
$x = 5$
it will take 5 hours.
