The diagram, not drawn to scale, shows the distances between 4 towns.
- Cathy travels from Town Q to Town R and then to Town T. 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 Town R to Town S.
- Find the shortest distance to travel from Town Q to Town T. Leave your answer in km and m.
(a)
Distance that Cathy has travelled
= 11.4 + 12.6
= 24 km
1 km = 1000 m
24 km = 24000 m
(b)
Cost of petrol consumption to travel from Town R to Town S
= 2.72 x 0.75
= $2.04
(c)
Distance to travel from Town Q to Town T via Town R
= 13.4 + 7.8
= 21.2 km (Shorter distance)
Distance to travel from Town Q to Town T via Town S
= 11.4 + 12.6
= 24 km (Longer distance)
Shortest distance to travel from Town Q to Town T = 21 km 200 m
Answer(s): (a) 24000 m; (b) $2.04; (c) 21 km 200 m
