The diagram, not drawn to scale, shows the distances between 4 buildings.
- Gillian 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 50 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 Gillian has travelled
= 11.3 + 12.7
= 24 km
1 km = 1000 m
24 km = 24000 m
(b)
Cost of petrol consumption to travel from Building B to Building C
= 3.22 x 0.50
= $1.61
(c)
Distance to travel from Building A to Building D via Building B
= 13.6 + 7.7
= 21.3 km (Shorter distance)
Distance to travel from Building A to Building D via Building C
= 11.3 + 12.7
= 24 km (Longer distance)
Shortest distance to travel from Building A to Building D = 21 km 300 m
Answer(s): (a) 24000 m; (b) $1.61; (c) 21 km 300 m
