The diagram, not drawn to scale, shows the distances between 4 cities.
- Cathy travels from City A to City B and then to City D. 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 B to City C.
- Find the shortest distance to travel from City A to City D. Leave your answer in km and m.
(a)
Distance that Cathy has travelled
= 11.8 + 15.2
= 27 km
1 km = 1000 m
27 km = 27000 m
(b)
Cost of petrol consumption to travel from City B to City C
= 3.74 x 0.50
= $1.87
(c)
Distance to travel from City A to City D via City B
= 15.1 + 9.2
= 24.3 km (Shorter distance)
Distance to travel from City A to City D via City C
= 11.8 + 15.2
= 27 km (Longer distance)
Shortest distance to travel from City A to City D = 24 km 300 m
Answer(s): (a) 27000 m; (b) $1.87; (c) 24 km 300 m
