The diagram, not drawn to scale, shows the distances between 4 towns.
- Usha travels from Town K to Town L and then to Town N. 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 L to Town M.
- Find the shortest distance to travel from Town K to Town N. Leave your answer in km and m.
(a)
Distance that Usha has travelled
= 13.3 + 17.7
= 31 km
1 km = 1000 m
31 km = 31000 m
(b)
Cost of petrol consumption to travel from Town L to Town M
= 3.82 x 0.50
= $1.91
(c)
Distance to travel from Town K to Town N via Town L
= 14.4 + 6.3
= 20.7 km (Shorter distance)
Distance to travel from Town K to Town N via Town M
= 13.3 + 17.7
= 31 km (Longer distance)
Shortest distance to travel from Town K to Town N = 20 km 700 m
Answer(s): (a) 31000 m; (b) $1.91; (c) 20 km 700 m
