Question
for x 5. Set up the following application problem and don't forget to DECLARE your variable. Solve the application and state your solution (rounded to 2 decimal place accuracy). Calvin Culus has just arrived in Chicago's O'Hare Airport for the annual TI Calculator conference. The moving sidewalk at O'Hare moves at a speed of 2 ft/sec. As Cal walks on the sidewalk he notices that he can travel 110 feet with the sidewalk in the same time that it would take him to travel 80 feet against the sidewalk (the opposite direction). Find is Cal's normal walking speed.Explanation / Answer
speed of moving sidewalk = 2ft/ sec
let w = normal walking speed
setting up the equation
110/ w+ 2 = 80 / w - 2
cross multiplying
110 ( w- 2) = 80 ( w+2)
110w - 220 = 80 w + 160
w = 38/3
Cal's normal walking speed = 12.67 feet / sec
