Traveling at an average speed of 50 miles per hour, the trip from point a to point b takes 2 hours. traveling at an average speed of 40 miles per hour, the same trip takes 2.5 hours. if time, y, varies inversely with speed, x, how long will the trip take traveling at 45 miles per hour? round your answer to the nearest hundredth, if necessary. hours

So, we're told that y, the time, varies inversely with the speed, x, which means:

Where y is time in hours, and x is your speed. To find k, we can use either examples tated, so let's use the first one since they're both integers.

So, now that we have our k we can find our missing time in the last example.

"exterior angles = 360 / number of sides.

60 = 360 / sides

sides = 360 / 60

sides = 6"
