The diagram, not drawn to scale, shows the distances between 4 cities.
- Yoko travels from City H to City J and then to City L. 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 J to City K.
- Find the shortest distance to travel from City H to City L. Leave your answer in km and m.
(a)
Distance that Yoko has travelled
= 11.2 + 12.8
= 24 km
1 km = 1000 m
24 km = 24000 m
(b)
Cost of petrol consumption to travel from City J to City K
= 2.76 x 0.75
= $2.07
(c)
Distance to travel from City H to City L via City J
= 14.2 + 6.7
= 20.9 km (Shorter distance)
Distance to travel from City H to City L via City K
= 11.2 + 12.8
= 24 km (Longer distance)
Shortest distance to travel from City H to City L = 20 km 900 m
Answer(s): (a) 24000 m; (b) $2.07; (c) 20 km 900 m
