Two cyclists, Isabella and Maria, are having a race. They both travel along a straight road with constant acceleration, starting from rest at point A. Isabella accelerates for 5 s at a constant rate a ms⁻². She then travels at the constant speed she has reached for 10 s, before decelerating to rest at a constant rate over a period of 5 s. Maria accelerates at a constant rate, reaching a speed of 5 ms⁻¹ in a distance of 27.5 m. She then maintains this speed for a period of 10s, before decelerating to rest at a constant rate over a period of 5 s.
