The diagram, not drawn to scale, shows the distances between 4 buildings.
- Cindy travels from Building A to Building B and then to Building D. Find the distance she has travelled in metres.
- The cost of petrol consumption for every km travelled is 60 cents. Find the cost of the petrol consumption to travel from Building B to Building C.
- Find the shortest distance to travel from Building A to Building D. Leave your answer in km and m.
(a)
Distance that Cindy has travelled
= 11.4 + 12.6
= 24 km
1 km = 1000 m
24 km = 24000 m
(b)
Cost of petrol consumption to travel from Building B to Building C
= 2.65 x 0.60
= $1.59
(c)
Distance to travel from Building A to Building D via Building B
= 15.2 + 7.4
= 22.6 km (Shorter distance)
Distance to travel from Building A to Building D via Building C
= 11.4 + 12.6
= 24 km (Longer distance)
Shortest distance to travel from Building A to Building D = 22 km 600 m
Answer(s): (a) 24000 m; (b) $1.59; (c) 22 km 600 m
