Question 1.3: On the London underground, Oxford Circus and Piccadilly Circ...

An Introduction to Mathematics for Engineers: Mechanics

On the London underground, Oxford Circus and Piccadilly Circus are 0.8 km apart. A train accelerates uniformly to a maximum speed when leaving Oxford Circus and maintains this speed for 90 s before decelerating uniformly to stop at Piccadilly Circus.
The whole journey takes 2 minutes. Find the maximum speed.
