### Instruction: two boats are heading towards each other at constant speeds of 4 miles / hr and 20 miles / hr respectively . they begin at a distance 20 miles from each other . how far are they ( in miles ) one minute before they collide ? Let's write a Python program to solve it.### Response: n0 = 4.0
n1 = 20.0
n2 = 20.0
t0 = n0 + n1
answer = t0 / 60.0
