You are to drive to an interview in another town, at a distance of 300km. You leave for the interview 3 ¼ hours before it is scheduled, planning to drive at 100 km/hr. You drive at that speed for the first 100 km. Then, construction work on the road causes you to drive at 40 km/hr for 60 km. At what constant speed must you drive the rest of the way to get to the interview on time.

A hare and a tortoise compete in a race over a course 1.00 km long. The tortoise craws straight and steadily at its maximum speed of 0.200 m/s toward the finish line. The hare runs at its maximum speed 8.00 m/s toward the goal for 0.800 km and then stops to tease the the tortoise. How close to the goal can the hare let the tortoise wins in a photo finish? Assume that, when moving, both animals move steadily at their respective maximum speeds. Pls include figures and fbd.
