Winston and alice are taking a trip. winston left at 8am and traveled an average of 50 miles per hour. alice left at 10am and traveled an average of 70 miles per hour. at what time are they at the same place at the same time? write a system of equations to represent this situation. then use the substitution method with that system to determine at what time they will be in the same location. how many miles away from home will they be at that time?

Statement reason 1. δabc is similar to δced. given 2. 3. definition of slope 4. slope of slope of definition of slope 5. slope of × slope of multiplying the slopes 6. slope of × slope of substitution property of equality 7. slope of × slope of simplifying the right side the table contains the proof of the relationship between the slopes of two perpendicular lines. what is the reason for statement 2? a. parallel line segments that meet a common perpendicular line are proportional in length. b. the lengths of vertical and horizontal sides in congruent triangles are in a common ratio. c. trigonometric identities determine the lengths of the legs in a right triangle. d. corresponding side lengths in similar triangles are proportional in length.
