The diagram, not drawn to scale, shows the distances between 4 offices.
- Tammy travels from Office Z to Office A and then to Office C. Find the distance she has travelled in metres.
- The cost of petrol consumption for every km travelled is 80 cents. Find the cost of the petrol consumption to travel from Office A to Office B.
- Find the shortest distance to travel from Office Z to Office C. Leave your answer in km and m.
(a)
Distance that Tammy has travelled
= 13.3 + 11.7
= 25 km
1 km = 1000 m
25 km = 25000 m
(b)
Cost of petrol consumption to travel from Office A to Office B
= 2.65 x 0.80
= $2.12
(c)
Distance to travel from Office Z to Office C via Office A
= 13.1 + 8.4
= 21.5 km (Shorter distance)
Distance to travel from Office Z to Office C via Office B
= 13.3 + 11.7
= 25 km (Longer distance)
Shortest distance to travel from Office Z to Office C = 21 km 500 m
Answer(s): (a) 25000 m; (b) $2.12; (c) 21 km 500 m
