The diagram, not drawn to scale, shows the distances between 4 cities.
- Cindy travels from City Y to City Z and then to City B. 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 Z to City A.
- Find the shortest distance to travel from City Y to City B. Leave your answer in km and m.
(a)
Distance that Cindy has travelled
= 12.8 + 14.2
= 27 km
1 km = 1000 m
27 km = 27000 m
(b)
Cost of petrol consumption to travel from City Z to City A
= 2.16 x 0.75
= $1.62
(c)
Distance to travel from City Y to City B via City Z
= 13.8 + 6.5
= 20.3 km (Shorter distance)
Distance to travel from City Y to City B via City A
= 12.8 + 14.2
= 27 km (Longer distance)
Shortest distance to travel from City Y to City B = 20 km 300 m
Answer(s): (a) 27000 m; (b) $1.62; (c) 20 km 300 m
