Question

Observe the picture and answer the following.

Find all the possible routes between B and F with distance. Mention the shortest route

Answer 1

All possible routes between B and F are:

(a) Route 1: B ➝ A ➝ G ➝ F

Distance = 250 m + 100 m + 150 m

= 600 m

(b) Route 2: B ➝ D ➝ E ➝ F

Distance = 100 m + 120 m + 300 m

= 520 m

(c) Route 3: B ➝ D ➝ G ➝ F

Distance = 100 m + 200 m + 150 m

= 450 m

(d) Route 4: B ➝ C ➝ D ➝ E ➝ F

Distance = 120 m + 200 m + 120 m + 300 m

= 740 m

We find that Route 3 is shortest.

ie B ➝ D ➝ G ➝ F is the shortest route.
