The diagram, not drawn to scale, shows the distances between 4 villages.
- Barbara 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 Barbara has travelled
= 10.6 + 18.4
= 29 km
1 km = 1000 m
29 km = 29000 m
(b)
Cost of petrol consumption to travel from Village Q to Village R
= 2.85 x 0.60
= $1.71
(c)
Distance to travel from Village P to Village S via Village Q
= 14.5 + 7.1
= 21.6 km (Shorter distance)
Distance to travel from Village P to Village S via Village R
= 10.6 + 18.4
= 29 km (Longer distance)
Shortest distance to travel from Village P to Village S = 21 km 600 m
Answer(s): (a) 29000 m; (b) $1.71; (c) 21 km 600 m
