The diagram, not drawn to scale, shows the distances between 4 villages.
- Dana travels from Village J to Village K and then to Village M. Find the distance she has travelled in metres.
- The cost of petrol consumption for every km travelled is 50 cents. Find the cost of the petrol consumption to travel from Village K to Village L.
- Find the shortest distance to travel from Village J to Village M. Leave your answer in km and m.
(a)
Distance that Dana has travelled
= 12.2 + 16.8
= 29 km
1 km = 1000 m
29 km = 29000 m
(b)
Cost of petrol consumption to travel from Village K to Village L
= 2.68 x 0.50
= $1.34
(c)
Distance to travel from Village J to Village M via Village K
= 14.3 + 6.3
= 20.6 km (Shorter distance)
Distance to travel from Village J to Village M via Village L
= 12.2 + 16.8
= 29 km (Longer distance)
Shortest distance to travel from Village J to Village M = 20 km 600 m
Answer(s): (a) 29000 m; (b) $1.34; (c) 20 km 600 m
