The diagram, not drawn to scale, shows the distances between 4 cities.
- Zara travels from City L to City M and then to City P. 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 City M to City N.
- Find the shortest distance to travel from City L to City P. Leave your answer in km and m.
(a)
Distance that Zara has travelled
= 10.1 + 19.9
= 30 km
1 km = 1000 m
30 km = 30000 m
(b)
Cost of petrol consumption to travel from City M to City N
= 3.15 x 0.80
= $2.52
(c)
Distance to travel from City L to City P via City M
= 15.8 + 7.7
= 23.5 km (Shorter distance)
Distance to travel from City L to City P via City N
= 10.1 + 19.9
= 30 km (Longer distance)
Shortest distance to travel from City L to City P = 23 km 500 m
Answer(s): (a) 30000 m; (b) $2.52; (c) 23 km 500 m
