The diagram, not drawn to scale, shows the distances between 4 buildings.
- Betty travels from Building K to Building L and then to Building 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 Building L to Building M.
- Find the shortest distance to travel from Building K to Building N. Leave your answer in km and m.
(a)
Distance that Betty has travelled
= 13.5 + 13.5
= 27 km
1 km = 1000 m
27 km = 27000 m
(b)
Cost of petrol consumption to travel from Building L to Building M
= 2.12 x 0.50
= $1.06
(c)
Distance to travel from Building K to Building N via Building L
= 15.6 + 9.7
= 25.3 km (Shorter distance)
Distance to travel from Building K to Building N via Building M
= 13.5 + 13.5
= 27 km (Longer distance)
Shortest distance to travel from Building K to Building N = 25 km 300 m
Answer(s): (a) 27000 m; (b) $1.06; (c) 25 km 300 m
