The diagram, not drawn to scale, shows the distances between 4 towns.
- Opal travels from Town M to Town N and then to Town Q. 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 Town N to Town P.
- Find the shortest distance to travel from Town M to Town Q. Leave your answer in km and m.
(a)
Distance that Opal has travelled
= 13.2 + 11.8
= 25 km
1 km = 1000 m
25 km = 25000 m
(b)
Cost of petrol consumption to travel from Town N to Town P
= 2.56 x 0.75
= $1.92
(c)
Distance to travel from Town M to Town Q via Town N
= 14.1 + 7.7
= 21.8 km (Shorter distance)
Distance to travel from Town M to Town Q via Town P
= 13.2 + 11.8
= 25 km (Longer distance)
Shortest distance to travel from Town M to Town Q = 21 km 800 m
Answer(s): (a) 25000 m; (b) $1.92; (c) 21 km 800 m
