Solve the all parts of following problem given below:
Problem: A hare and a tortoise compete in a race over a straight course 2.10 km long. The tortoise crawls at a speed of 0.180 m/s toward the finish line. The hare runs at a speed of 8.70 m/s toward the finish line for 1.680 km and then stops to tease the slow-moving tortoise as the tortoise eventually passes by. The hare waits for a while after the tortoise passes and then runs toward the finish line again at 8.70 m/s. Both the hare and the tortoise cross the finish line at the exact same instant. Assume both animals, when moving, move steadily at their respective speeds.
Part A: How far is the tortoise from the finish line when the hare resumes the race?
m
Part B: For how long in time was the hare stationary?
s
