Gemma is on a coach trip. After a short sleep she has woken up just in time to see this sign on the side of the motorway.The last thing she remembers seeing before she fell asleep is this sign:How far has the coach travelled while Gemma has been asleep?
Correct answer: C. 39km
- A. 4km
- B. 17km
- C. 39km
- D. 56km
Explanation
We can judge how far the coach travelled by picking up a data point common in both signs. In the first sign, Targen is at a distance of 7km from the coach, whereas in the second sign, Targen is at a distance of 46km from the coach.How far Gemma has travelled = 46km - 7km = 39kmTherefore, Option C is the answer.
