The diagram, not drawn to scale, shows the distances between 4 villages.
- Natalie travels from Village R to Village S and then to Village U. Find the distance she has travelled in metres.
- The cost of petrol consumption for every km travelled is 80 cents. Find the cost of the petrol consumption to travel from Village S to Village T.
- Find the shortest distance to travel from Village R to Village U. Leave your answer in km and m.
(a)
Distance that Natalie has travelled
= 13.4 + 14.6
= 28 km
1 km = 1000 m
28 km = 28000 m
(b)
Cost of petrol consumption to travel from Village S to Village T
= 2.15 x 0.80
= $1.72
(c)
Distance to travel from Village R to Village U via Village S
= 15.8 + 9.5
= 25.3 km (Shorter distance)
Distance to travel from Village R to Village U via Village T
= 13.4 + 14.6
= 28 km (Longer distance)
Shortest distance to travel from Village R to Village U = 25 km 300 m
Answer(s): (a) 28000 m; (b) $1.72; (c) 25 km 300 m
