The diagram, not drawn to scale, shows the distances between 4 buildings.
- Jane travels from Building G to Building H and then to Building K. 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 H to Building J.
- Find the shortest distance to travel from Building G to Building K. Leave your answer in km and m.
(a)
Distance that Jane has travelled
= 13.8 + 16.2
= 30 km
1 km = 1000 m
30 km = 30000 m
(b)
Cost of petrol consumption to travel from Building H to Building J
= 2.44 x 0.75
= $1.83
(c)
Distance to travel from Building G to Building K via Building H
= 14.8 + 8.4
= 23.2 km (Shorter distance)
Distance to travel from Building G to Building K via Building J
= 13.8 + 16.2
= 30 km (Longer distance)
Shortest distance to travel from Building G to Building K = 23 km 200 m
Answer(s): (a) 30000 m; (b) $1.83; (c) 23 km 200 m
