The diagram, not drawn to scale, shows the distances between 4 houses.
- Xuan travels from House Y to House Z and then to House B. 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 Z to House A.
- Find the shortest distance to travel from House Y to House B. Leave your answer in km and m.
(a)
Distance that Xuan has travelled
= 10.2 + 15.8
= 26 km
1 km = 1000 m
26 km = 26000 m
(b)
Cost of petrol consumption to travel from House Z to House A
= 3.74 x 0.50
= $1.87
(c)
Distance to travel from House Y to House B via House Z
= 13.7 + 9.8
= 23.5 km (Shorter distance)
Distance to travel from House Y to House B via House A
= 10.2 + 15.8
= 26 km (Longer distance)
Shortest distance to travel from House Y to House B = 23 km 500 m
Answer(s): (a) 26000 m; (b) $1.87; (c) 23 km 500 m
