You are flying from Houston to Chicago. You leave Houston at 7:30 A.M. At 8:35 A.M. you fly over Little Rock, a distance of 455 miles.

27. Write a linear equation that gives the distance in miles, y, in terms of time, x. Let x represent the pumber of minutes since 7:30 A.M.

28. Approximately what time will you arrive in Chicago if it is 950 miles from Houston?

​

Answer:

For a uniform move, the traveled distance equation is

y = v*x

where "v" is the average speed (or rate), in miles per minute, x is the time, in minutes.

To find "v" from the given data, divide 455 miles by 65 minutes (the flight time between the cities)

v = 455%2F65 = 7 miles per minute.

So, finally, your equation is

y = 7x.
