The diagram, not drawn to scale, shows the distances between 4 villages.
- Shiyun travels from Village P to Village Q and then to Village S. Find the distance she has travelled in metres.
- The cost of petrol consumption for every km travelled is 60 cents. Find the cost of the petrol consumption to travel from Village Q to Village R.
- Find the shortest distance to travel from Village P to Village S. Leave your answer in km and m.
(a)
Distance that Shiyun has travelled
= 10.7 + 17.3
= 28 km
1 km = 1000 m
28 km = 28000 m
(b)
Cost of petrol consumption to travel from Village Q to Village R
= 2.75 x 0.60
= $1.65
(c)
Distance to travel from Village P to Village S via Village Q
= 13.8 + 7.3
= 21.1 km (Shorter distance)
Distance to travel from Village P to Village S via Village R
= 10.7 + 17.3
= 28 km (Longer distance)
Shortest distance to travel from Village P to Village S = 21 km 100 m
Answer(s): (a) 28000 m; (b) $1.65; (c) 21 km 100 m
