The diagram, not drawn to scale, shows the distances between 4 towns.
- Rachel travels from Town V to Town W and then to Town Y. 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 Town W to Town X.
- Find the shortest distance to travel from Town V to Town Y. Leave your answer in km and m.
(a)
Distance that Rachel has travelled
= 10.1 + 19.9
= 30 km
1 km = 1000 m
30 km = 30000 m
(b)
Cost of petrol consumption to travel from Town W to Town X
= 2.14 x 0.50
= $1.07
(c)
Distance to travel from Town V to Town Y via Town W
= 15.2 + 8.2
= 23.4 km (Shorter distance)
Distance to travel from Town V to Town Y via Town X
= 10.1 + 19.9
= 30 km (Longer distance)
Shortest distance to travel from Town V to Town Y = 23 km 400 m
Answer(s): (a) 30000 m; (b) $1.07; (c) 23 km 400 m
