A hare and a tortoise are racing between two trees 150 feet apart. The tortoise has
a headstart of 30 seconds, but the hare catches up in 5 seconds. The hare then

again 10 seconds later (the hare has now run a total of 15 seconds). What is the
speed of each, assuming that they remain constant throughout the race?
