Answer:
5.5 km
Step-by-step explanation:
P.S - The exact question is -
As from the figure , we can see that
2 square = 1 km
Now,
Number of squares between P and Q = 4
Number of square between Q and R = 7
So,
Total number of squares = Number of squares between P and Q + Number of squares between Q and R
                     = 4 + 7 = 11
⇒Total number of squares = 11
Now as
2 squares = 1 km
⇒ 1 square = [tex]\frac{1}{2} km[/tex]
⇒11 square = [tex]\frac{11}{2} km = 5.5 km[/tex]
∴ we get
total distance, x + y = 5.5 km
