The diagram, not drawn to scale, shows the distances between 4 buildings.
- Xuan travels from Building H to Building J and then to Building L. 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 J to Building K.
- Find the shortest distance to travel from Building H to Building L. Leave your answer in km and m.
(a)
Distance that Xuan has travelled
= 12.9 + 11.1
= 24 km
1 km = 1000 m
24 km = 24000 m
(b)
Cost of petrol consumption to travel from Building J to Building K
= 2.42 x 0.50
= $1.21
(c)
Distance to travel from Building H to Building L via Building J
= 14.6 + 6.3
= 20.9 km (Shorter distance)
Distance to travel from Building H to Building L via Building K
= 12.9 + 11.1
= 24 km (Longer distance)
Shortest distance to travel from Building H to Building L = 20 km 900 m
Answer(s): (a) 24000 m; (b) $1.21; (c) 20 km 900 m
