The diagram, not drawn to scale, shows the distances between 4 cities.
- Yoko 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 75 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 Yoko has travelled
= 12.6 + 18.4
= 31 km
1 km = 1000 m
31 km = 31000 m
(b)
Cost of petrol consumption to travel from City F to City G
= 2.12 x 0.75
= $1.59
(c)
Distance to travel from City E to City H via City F
= 15.5 + 8.8
= 24.3 km (Shorter distance)
Distance to travel from City E to City H via City G
= 12.6 + 18.4
= 31 km (Longer distance)
Shortest distance to travel from City E to City H = 24 km 300 m
Answer(s): (a) 31000 m; (b) $1.59; (c) 24 km 300 m
