The diagram, not drawn to scale, shows the distances between 4 buildings.
- Kylie 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 50 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 Kylie has travelled
= 10.1 + 17.9
= 28 km
1 km = 1000 m
28 km = 28000 m
(b)
Cost of petrol consumption to travel from Building Q to Building R
= 3.78 x 0.50
= $1.89
(c)
Distance to travel from Building P to Building S via Building Q
= 14.9 + 9.9
= 24.8 km (Shorter distance)
Distance to travel from Building P to Building S via Building R
= 10.1 + 17.9
= 28 km (Longer distance)
Shortest distance to travel from Building P to Building S = 24 km 800 m
Answer(s): (a) 28000 m; (b) $1.89; (c) 24 km 800 m
