UPSEE 2018 Solved Paper

A train travels east towards Hubli at 80km∕h. A man on the train runs from the front of the train toward the rear of the train at 10km∕h with respect to train. As he runs, he carries a plate of fruit with him. He notices a giant spider on the plate and throws the plate away from him (toward the rear of the train) at 20km∕h with respect to him. Just after that instant, the startled spider jumps towards the man at 5km∕h with respect to plate. The instant after the spider jumps toward the man, how fast is the spider approaching Hubli?
