The diagram, not drawn to scale, shows the distances between 4 towns.
- Pamela travels from Town J to Town K and then to Town M. 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 K to Town L.
- Find the shortest distance to travel from Town J to Town M. Leave your answer in km and m.
(a)
Distance that Pamela has travelled
= 13.4 + 15.6
= 29 km
1 km = 1000 m
29 km = 29000 m
(b)
Cost of petrol consumption to travel from Town K to Town L
= 3.84 x 0.50
= $1.92
(c)
Distance to travel from Town J to Town M via Town K
= 13.4 + 8.7
= 22.1 km (Shorter distance)
Distance to travel from Town J to Town M via Town L
= 13.4 + 15.6
= 29 km (Longer distance)
Shortest distance to travel from Town J to Town M = 22 km 100 m
Answer(s): (a) 29000 m; (b) $1.92; (c) 22 km 100 m
