The diagram, not drawn to scale, shows the distances between 4 buildings.
- Emily travels from Building P to Building Q and then to Building S. 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 Q to Building R.
- Find the shortest distance to travel from Building P to Building S. Leave your answer in km and m.
(a)
Distance that Emily has travelled
= 10.8 + 16.2
= 27 km
1 km = 1000 m
27 km = 27000 m
(b)
Cost of petrol consumption to travel from Building Q to Building R
= 2.85 x 0.60
= $1.71
(c)
Distance to travel from Building P to Building S via Building Q
= 15.6 + 8.3
= 23.9 km (Shorter distance)
Distance to travel from Building P to Building S via Building R
= 10.8 + 16.2
= 27 km (Longer distance)
Shortest distance to travel from Building P to Building S = 23 km 900 m
Answer(s): (a) 27000 m; (b) $1.71; (c) 23 km 900 m
