The diagram, not drawn to scale, shows the distances between 4 houses.
- Jen travels from House W to House X and then to House Z. 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 House X to House Y.
- Find the shortest distance to travel from House W to House Z. Leave your answer in km and m.
(a)
Distance that Jen has travelled
= 11.5 + 16.5
= 28 km
1 km = 1000 m
28 km = 28000 m
(b)
Cost of petrol consumption to travel from House X to House Y
= 2.92 x 0.75
= $2.19
(c)
Distance to travel from House W to House Z via House X
= 14.5 + 6.1
= 20.6 km (Shorter distance)
Distance to travel from House W to House Z via House Y
= 11.5 + 16.5
= 28 km (Longer distance)
Shortest distance to travel from House W to House Z = 20 km 600 m
Answer(s): (a) 28000 m; (b) $2.19; (c) 20 km 600 m
