The diagram, not drawn to scale, shows the distances between 4 buildings.
- Winnie travels from Building R to Building S and then to Building U. Find the distance she has travelled in metres.
- The cost of petrol consumption for every km travelled is 60 cents. Find the cost of the petrol consumption to travel from Building S to Building T.
- Find the shortest distance to travel from Building R to Building U. Leave your answer in km and m.
(a)
Distance that Winnie has travelled
= 11.4 + 16.6
= 28 km
1 km = 1000 m
28 km = 28000 m
(b)
Cost of petrol consumption to travel from Building S to Building T
= 2.85 x 0.60
= $1.71
(c)
Distance to travel from Building R to Building U via Building S
= 13.2 + 7.5
= 20.7 km (Shorter distance)
Distance to travel from Building R to Building U via Building T
= 11.4 + 16.6
= 28 km (Longer distance)
Shortest distance to travel from Building R to Building U = 20 km 700 m
Answer(s): (a) 28000 m; (b) $1.71; (c) 20 km 700 m
