Try these (Text Book Page No. 119)

Question 1.
Observe the pictures and answer the following.
(i) Find all the possible routes from house to school via fire station.
(ii) Find all the possible routes between central park and school with distance. Mention the shortest route?
(iii) Calculate the shortest distance between bank and school.

(b) House ➝ Fire station ➝ Library ➝ Fruit shop ➝ School.
(c) House ➝ Fire station ➝ Library ➝ School.

(ii) Possible routes between Central park and school and their distances are
(a) School ➝ Fruit shop ➝ Hotel ➝ Central park.
Distance ➝ (150 + 300 + 100)m = 550 m

(b) School ➝ Fruit shop ➝ Library ➝ Central park Distance ➝(150 + 100 + 200)m
= 450 m

(c) School ➝ Library ➝ Central park
Distance = (20 + 200 m)
= 220 m

(d) School ➝ Library ➝ Fire station ➝ House ➝ central park Distance = (20 + 50 + 300 + 150) m
= 520 m

(e) School ➝ Emit shop ➝ Hotel ➝ Bank ➝ House ➝ Central park
Distance ➝ (150 + 300 + 150 + 200 + 150) m
= 950 m

(f) School ➝ fruit shop ➝ Hotel ➝ Bank ➝ House ➝ Fire station ➝ Library ➝ central park
Distance = (150 + 300 + 150 + 200 + 300 + 50 + 200)m = 1350 m
∴ Route (c) is the shortest path (i.e.,) School ➝ Library ➝ Central park

(iii) Shortest distance between school and Bank is calculated as follows Bank ➝ Hotel ➝ Central park ➝ Library ➝ school.
Distance = (150 + 100 + 200 + 20)m
= 470 m

Solution:
(i) (a) 700 m + 8.1 km = 700 m + (8 km + 100 m) = 8 km + 800 m = 8.8 km
(b) 700 m+ 1.7 km + 1.5 km = 700 m + (1 km, 700 m) + 1 km 500 m
= 2 km + 1900 m
= 2 km + 1 km + 900 m
= 3 km + 900 m
= 3.9 km
From the Ooty Boat House, the Botanical Garden is at a distance of 3.9 km(shortest)
