The diagram, not drawn to scale, shows the distances between 4 towns.
- Gillian travels from Town Z to Town A and then to Town C. 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 Town A to Town B.
- Find the shortest distance to travel from Town Z to Town C. Leave your answer in km and m.
(a)
Distance that Gillian has travelled
= 11.9 + 18.1
= 30 km
1 km = 1000 m
30 km = 30000 m
(b)
Cost of petrol consumption to travel from Town A to Town B
= 2.44 x 0.50
= $1.22
(c)
Distance to travel from Town Z to Town C via Town A
= 13.4 + 7.1
= 20.5 km (Shorter distance)
Distance to travel from Town Z to Town C via Town B
= 11.9 + 18.1
= 30 km (Longer distance)
Shortest distance to travel from Town Z to Town C = 20 km 500 m
Answer(s): (a) 30000 m; (b) $1.22; (c) 20 km 500 m
