Group Project 3
Lois Lane is in trouble and will die in 4 seconds! Superman is 20 miles away, but Superman can fly at a speed given
by
p
v(t) = t t2 + 1
in miles per second. Will superman be able to get there in time to rescue her? You may want to use the fact that
173/2 ≈ 70. (Hint: The problem can be written as a differential equation. )
In your groups discuss the question and come to a consensus on the answer. For full credit you must, draw a picture
of the problem, clearly explain your equation and show all the work that leads to the final answer.
