The diagram, not drawn to scale, shows the distances between 4 cities.
- Eva travels from City T to City U and then to City W. Find the distance she has travelled in metres.
- The cost of petrol consumption for every km travelled is 75 cents. Find the cost of the petrol consumption to travel from City U to City V.
- Find the shortest distance to travel from City T to City W. Leave your answer in km and m.
(a)
Distance that Eva has travelled
= 10.7 + 20.3
= 31 km
1 km = 1000 m
31 km = 31000 m
(b)
Cost of petrol consumption to travel from City U to City V
= 3.64 x 0.75
= $2.73
(c)
Distance to travel from City T to City W via City U
= 13.7 + 9.4
= 23.1 km (Shorter distance)
Distance to travel from City T to City W via City V
= 10.7 + 20.3
= 31 km (Longer distance)
Shortest distance to travel from City T to City W = 23 km 100 m
Answer(s): (a) 31000 m; (b) $2.73; (c) 23 km 100 m
