The diagram, not drawn to scale, shows the distances between 4 cities.
- Zoe travels from City R to City S and then to City U. 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 S to City T.
- Find the shortest distance to travel from City R to City U. Leave your answer in km and m.
(a)
Distance that Zoe has travelled
= 13.7 + 14.3
= 28 km
1 km = 1000 m
28 km = 28000 m
(b)
Cost of petrol consumption to travel from City S to City T
= 2.32 x 0.50
= $1.16
(c)
Distance to travel from City R to City U via City S
= 15.8 + 9.3
= 25.1 km (Shorter distance)
Distance to travel from City R to City U via City T
= 13.7 + 14.3
= 28 km (Longer distance)
Shortest distance to travel from City R to City U = 25 km 100 m
Answer(s): (a) 28000 m; (b) $1.16; (c) 25 km 100 m
