# Travel with uniformly accelerated motion

Classical Mechanics Level pending

A car goes east at a speed of $$10 \text{ m/s}.$$ Then the car gets into uniformly accelerated motion for just $$10$$ seconds, and ends up heading back westward at a speed of $$30 \text{ m/s.}$$ What is the distance traveled by the car from the beginning of the acceleration to the moment the speed becomes zero?
