The diagram, not drawn to scale, shows the distances between 4 houses.
- Penelope travels from House H to House J and then to House L. 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 J to House K.
- Find the shortest distance to travel from House H to House L. Leave your answer in km and m.
(a)
Distance that Penelope has travelled
= 13.7 + 14.3
= 28 km
1 km = 1000 m
28 km = 28000 m
(b)
Cost of petrol consumption to travel from House J to House K
= 3.48 x 0.50
= $1.74
(c)
Distance to travel from House H to House L via House J
= 15.3 + 7.6
= 22.9 km (Shorter distance)
Distance to travel from House H to House L via House K
= 13.7 + 14.3
= 28 km (Longer distance)
Shortest distance to travel from House H to House L = 22 km 900 m
Answer(s): (a) 28000 m; (b) $1.74; (c) 22 km 900 m
