Question
A student walks x kilometers (km) along a straight path from point P to point Q. Then the student walks y km along a straight path from point Q to point R. What is the total distance, x + y, in km, that the student walks?
- 2.0
- 3.5
- 5.5
- 8.0
The correct answer is: 5.5
Two sides combine for 1 km.
From P to Q we have 4 sides ⇒ 2 km
From Q to R we have 7 sides ⇒ 3.5 km
The total distance = 2 + 3.5 = 5.5 km.
