The diagram, not drawn to scale, shows the distances between 4 villages.
- Kathy 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 50 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 Kathy 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 Q to Village R
= 3.52 x 0.50
= $1.76
(c)
Distance to travel from Village P to Village S via Village Q
= 15.3 + 7.6
= 22.9 km (Shorter distance)
Distance to travel from Village P to Village S via Village R
= 12.2 + 16.8
= 29 km (Longer distance)
Shortest distance to travel from Village P to Village S = 22 km 900 m
Answer(s): (a) 29000 m; (b) $1.76; (c) 22 km 900 m
