The diagram, not drawn to scale, shows the distances between 4 buildings.
- Lynn travels from Building Z to Building A and then to Building C. Find the distance she has travelled in metres.
- The cost of petrol consumption for every km travelled is 75 cents. Find the cost of the petrol consumption to travel from Building A to Building B.
- Find the shortest distance to travel from Building Z to Building C. Leave your answer in km and m.
(a)
Distance that Lynn has travelled
= 11.5 + 17.5
= 29 km
1 km = 1000 m
29 km = 29000 m
(b)
Cost of petrol consumption to travel from Building A to Building B
= 2.56 x 0.75
= $1.92
(c)
Distance to travel from Building Z to Building C via Building A
= 15.2 + 7.5
= 22.7 km (Shorter distance)
Distance to travel from Building Z to Building C via Building B
= 11.5 + 17.5
= 29 km (Longer distance)
Shortest distance to travel from Building Z to Building C = 22 km 700 m
Answer(s): (a) 29000 m; (b) $1.92; (c) 22 km 700 m
