The diagram, not drawn to scale, shows the distances between 4 cities.
- Shiyun travels from City S to City T and then to City V. 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 T to City U.
- Find the shortest distance to travel from City S to City V. Leave your answer in km and m.
(a)
Distance that Shiyun has travelled
= 13.8 + 14.2
= 28 km
1 km = 1000 m
28 km = 28000 m
(b)
Cost of petrol consumption to travel from City T to City U
= 2.95 x 0.80
= $2.36
(c)
Distance to travel from City S to City V via City T
= 15.2 + 6.6
= 21.8 km (Shorter distance)
Distance to travel from City S to City V via City U
= 13.8 + 14.2
= 28 km (Longer distance)
Shortest distance to travel from City S to City V = 21 km 800 m
Answer(s): (a) 28000 m; (b) $2.36; (c) 21 km 800 m
