Three Problems and Solutions (attachment)

: How much time will it take for a car to slow down from the highway speed of 35 m/s to a residential speed of 13.7 m/s if the brakes provide a deceleration of 4.11 m/s^2? I would appreciate step by step if possible. I really want to understand this and not just know the answer. Thank you so much in advance! Also, there is another problem I am stuck on. Help with it would also be appreciated: A 150 kg ninja is leaping at a pirate with a velocity of 7.3 m/s. The pirate is moving at a velocity of 4.1 m/s. What is the minimum mass of the pirate if it is not affected by the leap of the attacking ninja?? And yeah, my science teacher is a freak :]

Question:This is the question: a car covers a distance of 400 km at a speed of x km/h, and a train covers the same distance at (x + 10) km/h. If the time taken by the car is 10 hours more than the time taken by the train, then the exact answer of x is..? And I’m really quite confused. I’m just having trouble with the first step: getting a reference point and then going on to find the equation. once i have that, i’ll be fine
