The diagram, not drawn to scale, shows the distances between 4 houses.
- Erika travels from House X to House Y and then to House A. 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 House Y to House Z.
- Find the shortest distance to travel from House X to House A. Leave your answer in km and m.
(a)
Distance that Erika has travelled
= 13.4 + 14.6
= 28 km
1 km = 1000 m
28 km = 28000 m
(b)
Cost of petrol consumption to travel from House Y to House Z
= 3.34 x 0.50
= $1.67
(c)
Distance to travel from House X to House A via House Y
= 14.8 + 8.4
= 23.2 km (Shorter distance)
Distance to travel from House X to House A via House Z
= 13.4 + 14.6
= 28 km (Longer distance)
Shortest distance to travel from House X to House A = 23 km 200 m
Answer(s): (a) 28000 m; (b) $1.67; (c) 23 km 200 m
