The diagram, not drawn to scale, shows the distances between 4 offices.
- Tammy travels from Office W to Office X and then to Office Z. 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 Office X to Office Y.
- Find the shortest distance to travel from Office W to Office Z. Leave your answer in km and m.
(a)
Distance that Tammy has travelled
= 13.5 + 17.5
= 31 km
1 km = 1000 m
31 km = 31000 m
(b)
Cost of petrol consumption to travel from Office X to Office Y
= 2.24 x 0.50
= $1.12
(c)
Distance to travel from Office W to Office Z via Office X
= 13.1 + 6.8
= 19.9 km (Shorter distance)
Distance to travel from Office W to Office Z via Office Y
= 13.5 + 17.5
= 31 km (Longer distance)
Shortest distance to travel from Office W to Office Z = 19 km 900 m
Answer(s): (a) 31000 m; (b) $1.12; (c) 19 km 900 m
