The diagram, not drawn to scale, shows the distances between 4 offices.
- Opal travels from Office Q to Office R and then to Office T. 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 R to Office S.
- Find the shortest distance to travel from Office Q to Office T. Leave your answer in km and m.
(a)
Distance that Opal has travelled
= 12.3 + 18.7
= 31 km
1 km = 1000 m
31 km = 31000 m
(b)
Cost of petrol consumption to travel from Office R to Office S
= 2.95 x 0.80
= $2.36
(c)
Distance to travel from Office Q to Office T via Office R
= 15.3 + 7.6
= 22.9 km (Shorter distance)
Distance to travel from Office Q to Office T via Office S
= 12.3 + 18.7
= 31 km (Longer distance)
Shortest distance to travel from Office Q to Office T = 22 km 900 m
Answer(s): (a) 31000 m; (b) $2.36; (c) 22 km 900 m
