The diagram, not drawn to scale, shows the distances between 4 houses.
- Jen travels from House D to House E and then to House G. 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 E to House F.
- Find the shortest distance to travel from House D to House G. Leave your answer in km and m.
(a)
Distance that Jen has travelled
= 10.3 + 18.7
= 29 km
1 km = 1000 m
29 km = 29000 m
(b)
Cost of petrol consumption to travel from House E to House F
= 3.72 x 0.75
= $2.79
(c)
Distance to travel from House D to House G via House E
= 15.3 + 7.9
= 23.2 km (Shorter distance)
Distance to travel from House D to House G via House F
= 10.3 + 18.7
= 29 km (Longer distance)
Shortest distance to travel from House D to House G = 23 km 200 m
Answer(s): (a) 29000 m; (b) $2.79; (c) 23 km 200 m
