The diagram, not drawn to scale, shows the distances between 4 buildings.
- Nora 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 Nora has travelled
= 11.9 + 12.1
= 24 km
1 km = 1000 m
24 km = 24000 m
(b)
Cost of petrol consumption to travel from Building X to Building Y
= 3.14 x 0.50
= $1.57
(c)
Distance to travel from Building W to Building Z via Building X
= 13.5 + 9.7
= 23.2 km (Shorter distance)
Distance to travel from Building W to Building Z via Building Y
= 11.9 + 12.1
= 24 km (Longer distance)
Shortest distance to travel from Building W to Building Z = 23 km 200 m
Answer(s): (a) 24000 m; (b) $1.57; (c) 23 km 200 m
