The diagram, not drawn to scale, shows the distances between 4 cities.
- Roshel travels from City Q to City R and then to City T. 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 City R to City S.
- Find the shortest distance to travel from City Q to City T. Leave your answer in km and m.
(a)
Distance that Roshel has travelled
= 10.8 + 13.2
= 24 km
1 km = 1000 m
24 km = 24000 m
(b)
Cost of petrol consumption to travel from City R to City S
= 2.45 x 0.60
= $1.47
(c)
Distance to travel from City Q to City T via City R
= 15.1 + 8.1
= 23.2 km (Shorter distance)
Distance to travel from City Q to City T via City S
= 10.8 + 13.2
= 24 km (Longer distance)
Shortest distance to travel from City Q to City T = 23 km 200 m
Answer(s): (a) 24000 m; (b) $1.47; (c) 23 km 200 m
