Introduction to Distance-Rate-Time Applications Example 1: Jan drives south out of Denver and averages 65mph. How far is she from Denver after 3 hours. Use the formula … distance = rate × time Jan drove 195 miles.

Introduction to Distance-Rate-Time Applications Example 2: Write an expression for the distance traveled if the average rate is r mph and the time is 6 hours. Use the formula … distance = rate × time The distance is given by 6r.

A plane flies p mph in a wind that is 30 mph. Write expressions for the ground speed of the plane going: 1) With the wind 2) Against the wind Introduction to Distance-Rate-Time Applications Example 3:

1) Going with the wind, the planes ground speed is increased! The wind is helping the plane to fly at an increased rate. ground rate = (rate of plane) + (rate of wind)

2) Going against the wind, the planes ground speed is decreased! The wind is causing the plane to fly at an slower rate. ground rate = (rate of plane) - (rate of wind)
