The diagram, not drawn to scale, shows the distances between 4 cities.
- Emily travels from City G to City H and then to City K. 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 City H to City J.
- Find the shortest distance to travel from City G to City K. Leave your answer in km and m.
(a)
Distance that Emily has travelled
= 13.1 + 13.9
= 27 km
1 km = 1000 m
27 km = 27000 m
(b)
Cost of petrol consumption to travel from City H to City J
= 2.96 x 0.50
= $1.48
(c)
Distance to travel from City G to City K via City H
= 13.8 + 6.3
= 20.1 km (Shorter distance)
Distance to travel from City G to City K via City J
= 13.1 + 13.9
= 27 km (Longer distance)
Shortest distance to travel from City G to City K = 20 km 100 m
Answer(s): (a) 27000 m; (b) $1.48; (c) 20 km 100 m
