Question: A transmilenium feeder has stopped at a traffic light, starts moving and increases its speed uniformly up to 70 km / h after 10 s.

A transmilenium feeder has stopped at a traffic light, starts moving and increases its speed uniformly up to 70 km / h after 10 s. From that moment on, the speed remains constant for 0.25 minutes, after which the driver observes another traffic light that turns red, so the speed decreases uniformly until it stops 5 s after starting to brake. Determine the displacement between the two traffic lights, in each time interval.
