The diagram, not drawn to scale, shows the distances between 4 towns.
- Pamela travels from Town G to Town H and then to Town K. Find the distance she has travelled in metres.
- The cost of petrol consumption for every km travelled is 75 cents. Find the cost of the petrol consumption to travel from Town H to Town J.
- Find the shortest distance to travel from Town G to Town K. Leave your answer in km and m.
(a)
Distance that Pamela has travelled
= 12.2 + 16.8
= 29 km
1 km = 1000 m
29 km = 29000 m
(b)
Cost of petrol consumption to travel from Town H to Town J
= 2.76 x 0.75
= $2.07
(c)
Distance to travel from Town G to Town K via Town H
= 15.8 + 7.3
= 23.1 km (Shorter distance)
Distance to travel from Town G to Town K via Town J
= 12.2 + 16.8
= 29 km (Longer distance)
Shortest distance to travel from Town G to Town K = 23 km 100 m
Answer(s): (a) 29000 m; (b) $2.07; (c) 23 km 100 m
