so what you need to do is answer the problems at the top to make then into a answer that looks like (x, y) ,(a,b) and find it on the graphs
Answer:
12km/h
Step-by-step explana:
Let's call the total distance 2a from which we can calculate t1 equivalent to the first half of the distance a/10 similar to t2 is a/15 from which the total time is a/6 . We have the average speed equal to the total distance dduowcngf divided by the total inferred time by 2a/(a/6) which equals 12km/h
