The diagram, not drawn to scale, shows the distances between 4 towns.
- Barbara travels from Town H to Town J and then to Town L. 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 Town J to Town K.
- Find the shortest distance to travel from Town H to Town L. Leave your answer in km and m.
(a)
Distance that Barbara has travelled
= 12.2 + 18.8
= 31 km
1 km = 1000 m
31 km = 31000 m
(b)
Cost of petrol consumption to travel from Town J to Town K
= 2.05 x 0.60
= $1.23
(c)
Distance to travel from Town H to Town L via Town J
= 15.4 + 8.8
= 24.2 km (Shorter distance)
Distance to travel from Town H to Town L via Town K
= 12.2 + 18.8
= 31 km (Longer distance)
Shortest distance to travel from Town H to Town L = 24 km 200 m
Answer(s): (a) 31000 m; (b) $1.23; (c) 24 km 200 m
