The diagram, not drawn to scale, shows the distances between 4 houses.
- Elyse travels from House R to House S and then to House U. 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 S to House T.
- Find the shortest distance to travel from House R to House U. Leave your answer in km and m.
(a)
Distance that Elyse has travelled
= 13.8 + 12.2
= 26 km
1 km = 1000 m
26 km = 26000 m
(b)
Cost of petrol consumption to travel from House S to House T
= 3.55 x 0.60
= $2.13
(c)
Distance to travel from House R to House U via House S
= 15.3 + 6.5
= 21.8 km (Shorter distance)
Distance to travel from House R to House U via House T
= 13.8 + 12.2
= 26 km (Longer distance)
Shortest distance to travel from House R to House U = 21 km 800 m
Answer(s): (a) 26000 m; (b) $2.13; (c) 21 km 800 m
