The diagram above illustrates the motion of a cyclist from P to R. The distance travelled is determined by the
- area under QR
-
gradient of QR
- area under PQR
- gradient of PQR
The correct answer is: B
Explanation
The total area under the entire segment from P to R (the area of the triangle plus the area of the rectangle) represents the total distance traveled by the cyclist during the motion from P to R.
