When there is nо wind, а runner is аble tо run (19000 )m аt an average speed оf (x) m/s. When he runs with a tailwind, his average speed increases by (0.4) m/s and it takes him (10) s less to run the (19000) m. The equation shown below represents this relationship. 19000x−19000x+0.4=10,x>0 When there is no wind, what is the runner's average speed, to the nearest hundredth of a metre per second? What does each term of the given equation represent (Distance, Rate or, Time of what part of the scenario | ex: (Rate_against current) [2 mark] Explain your process of solving [1 Mark] State your solution [1 mark] Alternatively, Email me a photo of your written solution within 5 minutes of submitting your exam.
