The diagram, not drawn to scale, shows the distances between 4 buildings.
- Penelope travels from Building W to Building X and then to Building Z. 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 X to Building Y.
- Find the shortest distance to travel from Building W to Building Z. Leave your answer in km and m.
(a)
Distance that Penelope has travelled
= 11.8 + 13.2
= 25 km
1 km = 1000 m
25 km = 25000 m
(b)
Cost of petrol consumption to travel from Building X to Building Y
= 2.96 x 0.50
= $1.48
(c)
Distance to travel from Building W to Building Z via Building X
= 14.5 + 6.1
= 20.6 km (Shorter distance)
Distance to travel from Building W to Building Z via Building Y
= 11.8 + 13.2
= 25 km (Longer distance)
Shortest distance to travel from Building W to Building Z = 20 km 600 m
Answer(s): (a) 25000 m; (b) $1.48; (c) 20 km 600 m
