The diagram, not drawn to scale, shows the distances between 4 cities.
- Marion travels from City E to City F and then to City H. Find the distance she has travelled in metres.
- The cost of petrol consumption for every km travelled is 80 cents. Find the cost of the petrol consumption to travel from City F to City G.
- Find the shortest distance to travel from City E to City H. Leave your answer in km and m.
(a)
Distance that Marion has travelled
= 13.3 + 17.7
= 31 km
1 km = 1000 m
31 km = 31000 m
(b)
Cost of petrol consumption to travel from City F to City G
= 3.55 x 0.80
= $2.84
(c)
Distance to travel from City E to City H via City F
= 15.7 + 9.7
= 25.4 km (Shorter distance)
Distance to travel from City E to City H via City G
= 13.3 + 17.7
= 31 km (Longer distance)
Shortest distance to travel from City E to City H = 25 km 400 m
Answer(s): (a) 31000 m; (b) $2.84; (c) 25 km 400 m
