The diagram, not drawn to scale, shows the distances between 4 houses.
- Risa travels from House Q to House R and then to House T. 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 House R to House S.
- Find the shortest distance to travel from House Q to House T. Leave your answer in km and m.
(a)
Distance that Risa has travelled
= 10.6 + 17.4
= 28 km
1 km = 1000 m
28 km = 28000 m
(b)
Cost of petrol consumption to travel from House R to House S
= 3.65 x 0.60
= $2.19
(c)
Distance to travel from House Q to House T via House R
= 15.3 + 9.6
= 24.9 km (Shorter distance)
Distance to travel from House Q to House T via House S
= 10.6 + 17.4
= 28 km (Longer distance)
Shortest distance to travel from House Q to House T = 24 km 900 m
Answer(s): (a) 28000 m; (b) $2.19; (c) 24 km 900 m
