The diagram, not drawn to scale, shows the distances between 4 towns.
- Irene travels from Town U to Town V and then to Town X. 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 V to Town W.
- Find the shortest distance to travel from Town U to Town X. Leave your answer in km and m.
(a)
Distance that Irene has travelled
= 13.2 + 15.8
= 29 km
1 km = 1000 m
29 km = 29000 m
(b)
Cost of petrol consumption to travel from Town V to Town W
= 3.02 x 0.50
= $1.51
(c)
Distance to travel from Town U to Town X via Town V
= 14.3 + 6.8
= 21.1 km (Shorter distance)
Distance to travel from Town U to Town X via Town W
= 13.2 + 15.8
= 29 km (Longer distance)
Shortest distance to travel from Town U to Town X = 21 km 100 m
Answer(s): (a) 29000 m; (b) $1.51; (c) 21 km 100 m
