NAME Using Systems of Equations (continued)
NAME Using Systems of Equations (continued) Problem 2 With a head wind, a jet flew a certain distance in 4.0 h. The return trip was flown wi having the same speed as the head wind. The return trip took 24 min less than the ori; speed of the plane in still air was 475 km/h, find the total distance flown. a. Circle the quantities that are known. air speed wind speed ground speeds flying times distances flown b. Choose two variables to represent the unknown quantities and complete the chart. Let Let Ground speed Time Distance km/h h km going returning Be careful here. c. Write a system of equations, including one equation for each portion of the round trip d. Solve the system. e. Write your answer to the problem. f. Check: Compute the distance flown with a head wind. Compute the distance flown with a tail wind. Do your answers agree
