How do you know? If not, which is ahead? the cyclist do not start at the some point, pone cyclist to point a which starts at o distance white go the other goves Starts from & educatage but ends up goln less dis b. At t= 7s, which cyclist is ahead? How do you know? Cyclist that is going to point A is where since their position has gone up more as time progressed c. Which cyclist is travelling faster at t = 3s? How do you know? cyclist b is faster cat that time and is ahead since their position from the start gave the advantage d. Are their velocities equal at any time? How do you know? Yes since the exclists at that intersection 06 lines A and B crossed meaning at a point in time (5 seconds) they had equal times e. What is happening at the intersection of lines A and B?
