In attempting to fly from city P to city Q, an aircraft followed a course that was 10 degrees in error, as indicated in the figure. After flying a distance of 50 miles, the pilot corrected the course by turning at point R and flying 300 miles farther. If the constant seed of the aircraft was 250 miles per hour, how much time was lost due to the error? 10 300 mi E 50 mi R

Linear Functions

A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
