The diagram, not drawn to scale, shows the distances between 4 offices.
- Rachel travels from Office N to Office P and then to Office R. 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 P to Office Q.
- Find the shortest distance to travel from Office N to Office R. Leave your answer in km and m.
(a)
Distance that Rachel has travelled
= 11.1 + 15.9
= 27 km
1 km = 1000 m
27 km = 27000 m
(b)
Cost of petrol consumption to travel from Office P to Office Q
= 3.64 x 0.50
= $1.82
(c)
Distance to travel from Office N to Office R via Office P
= 14.4 + 8.8
= 23.2 km (Shorter distance)
Distance to travel from Office N to Office R via Office Q
= 11.1 + 15.9
= 27 km (Longer distance)
Shortest distance to travel from Office N to Office R = 23 km 200 m
Answer(s): (a) 27000 m; (b) $1.82; (c) 23 km 200 m
