To determine how many yards Marc walked from point P to point Q and then from point Q to point R, we first need to calculate the distances in blocks and then convert those distances into yards.
-
Distance from point P to point Q:
- Point Q is 5 blocks to the right of point P.
- Since each block is 120 yards, the distance from point P to point Q in yards is: \[ 5 \text{ blocks} \times 120 \text{ yards/block} = 600 \text{ yards} \]
-
Distance from point Q to point R:
- Point R is 3 blocks above point Q.
- The distance from point Q to point R in yards is: \[ 3 \text{ blocks} \times 120 \text{ yards/block} = 360 \text{ yards} \]
-
Total distance walked:
- To find the total distance Marc walked, we add the distances from P to Q and from Q to R: \[ 600 \text{ yards} + 360 \text{ yards} = 960 \text{ yards} \]
Thus, the total distance that Marc walked is 960 yards, which corresponds to answer C. 960 yards.
