The diagram, not drawn to scale, shows the distances between 4 buildings.
- Jen travels from Building E to Building F and then to Building H. 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 F to Building G.
- Find the shortest distance to travel from Building E to Building H. Leave your answer in km and m.
(a)
Distance that Jen has travelled
= 12.4 + 13.6
= 26 km
1 km = 1000 m
26 km = 26000 m
(b)
Cost of petrol consumption to travel from Building F to Building G
= 2.88 x 0.50
= $1.44
(c)
Distance to travel from Building E to Building H via Building F
= 13.3 + 9.6
= 22.9 km (Shorter distance)
Distance to travel from Building E to Building H via Building G
= 12.4 + 13.6
= 26 km (Longer distance)
Shortest distance to travel from Building E to Building H = 22 km 900 m
Answer(s): (a) 26000 m; (b) $1.44; (c) 22 km 900 m
