The diagram, not drawn to scale, shows the distances between 4 buildings.
- Sarah travels from Building S to Building T and then to Building V. 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 T to Building U.
- Find the shortest distance to travel from Building S to Building V. Leave your answer in km and m.
(a)
Distance that Sarah has travelled
= 12.3 + 16.7
= 29 km
1 km = 1000 m
29 km = 29000 m
(b)
Cost of petrol consumption to travel from Building T to Building U
= 3.75 x 0.60
= $2.25
(c)
Distance to travel from Building S to Building V via Building T
= 14.3 + 8.5
= 22.8 km (Shorter distance)
Distance to travel from Building S to Building V via Building U
= 12.3 + 16.7
= 29 km (Longer distance)
Shortest distance to travel from Building S to Building V = 22 km 800 m
Answer(s): (a) 29000 m; (b) $2.25; (c) 22 km 800 m
