The diagram, not drawn to scale, shows the distances between 4 offices.
- Barbara travels from Office B to Office C and then to Office E. 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 Office C to Office D.
- Find the shortest distance to travel from Office B to Office E. Leave your answer in km and m.
(a)
Distance that Barbara has travelled
= 10.2 + 13.8
= 24 km
1 km = 1000 m
24 km = 24000 m
(b)
Cost of petrol consumption to travel from Office C to Office D
= 3.45 x 0.60
= $2.07
(c)
Distance to travel from Office B to Office E via Office C
= 14.7 + 7.2
= 21.9 km (Shorter distance)
Distance to travel from Office B to Office E via Office D
= 10.2 + 13.8
= 24 km (Longer distance)
Shortest distance to travel from Office B to Office E = 21 km 900 m
Answer(s): (a) 24000 m; (b) $2.07; (c) 21 km 900 m
